In today’s day and age, with smart cell phones, and portable computers, we probably take home phone lines for granted. We don’t give it much thought but home phone lines have been an integral part of the advancement of our society, connecting us across vast countries and even between continents. Home phone lines actually run on power directly from the phone companies lines so that if the main power goes out, you’ll still get service.

Home phone lines are not just a convenience, they are part of our emergency response systems. People with home phone lines are able to dial 911 for help if they ever have an emergency. This system using home phone lines is responsible for saving countless lives. What would it be like now if people could not use home phone lines to call the police, say in the case of an intruder? Or what if there were no home phone lines and a fire broke out? What about if grandma falls and she can’t get up and there are no home phone lines for her to call for help with? Our emergency services are able to keep us safe because of the network of reliable home phone lines that are in almost every home today.

Before all that new fangled social networking and messaging stuff through the internet, home phone lines were the primary way for people to get in touch with their friends and family. They used home phone lines to make plans, check in on each other, and even to find the comfort of hearing someone’s voice. Home phone lines were a way for teens to talk to each other, after school, they probably hoped it was without their parents knowing.

Home phone lines have become more advanced over the years. Does anyone else remember the rotary pulse dial phones? Home phone lines went from that to touch tone. Eventually home phone lines started adding features like caller I.D., call waiting, voicemail, and even data features. Modern home phone lines continue to be trusted and reliable, and enhanced through these new features.

Today the use of home phone lines is declining somewhat with more people adopting cell phones as their only phone connection. But the infrastructure for home phone lines in North America is fully developed and will continue to prove useful well into the future. Home phone lines are an established standard that you really can’t go wrong with.

According to the latest roumors in the business world, there’s promise in the hosted telephone systems category. Hosted VoIP services are among the areas that are expected to boom. Business VoIP is really the area gaining foothold quickly with technologies such as Hosted PBX. Hosted PBX Solutions are starting a new chapter in improving customer service for small and medium sized businesses. Hosted PBX allow the same capabilities that large businesses only were once capable of providing, but this time around the cost is much lower. Up to this point, large companies were able to leverage the costs involved with on-site PBX systems that small to medium sized businesses could not afford because of the high initial cost.

VoIP has a number of advantages over traditional telephone networks, starting with the lack of need for expensive onsite equipment. Also, it’s not necessary to invest in multiple phone lines for the purposes of fax and internet separately. Hosted PBX and VoIP has all the solutions that businesses need to save on communication costs.

Hosted PBX can benefit an organization at low cost, with the flexibility that a remote swithc center provides. Hosted PBX services brings a new chapter in business communications.

The services provided by Hosted PBX include all the basic features of a regular PBX and more. This incldes a large number of extentions, welcome greetings and even toll free numbers. Features that are usually considered extras by companies utilizing reqular phone lines, such as conference calling, call forwarding, etc. are now basic with a VoIP based hosted PBX service.

VoIP based systems offer grater flsxibility as well, as it is possible to access the system from anywhere.

Levi Halberstam, CEO of Pop VoIP said, “Pop VoIP specializes in small businesses. We know what they require and cater to those needs with our telecommunications services.

Aging, some drugs, head injuries and excessive noise can all cause lasting damage to hearing. The most common type of permanent hearing loss results from excessive noise.

What causes noise-induced hearing loss?

• Loudness of a sound (decibels)
• Pitch of a sound
• Length of exposure

The loudness of a sound and the length of exposure are directly related. The louder the sound, the shorter the time it takes to damage hearing. Sound levels of less than 75 decibels are unlikely to cause permanent hearing loss. Sound levels above 85 decibels can be dangerous after prolonged exposure. Repeated, prolonged exposure (more than eight hours) to noise above 90 decibels (motorcycles and lawn mowers) can cause gradual hearing loss. Rock concerts generate sound levels between 110 and 140 decibels and can cause damage in less than 15 minutes. Some of the hearing damage is reversible, but repeated and prolonged exposures to excessive noise can result in permanent damage.

What are the danger signs of noise-induced hearing loss?

• Ringing or buzzing in the ears
• Difficulty understanding speech
• Slight muffling of sounds
• Difficulty understanding speech in noisy places or places with poor acoustics.
• Shouting to communicate

Are headphone users at risk of hearing loss?

Normal conversation measures around 60 decibels. If you listen to headphones and keep the volume at a normal conversational level, you are not at risk of hearing loss. Your headphone volume should be kept low enough so no one else can hear it.

Headphone users are susceptible to a decreasing sensitivity to sound levels over time, as the ears adapt to loud sounds. The listener perceives a gradual drop in loudness even though the volume is the same. It is important to avoid listening fatigue when working by taking hearing breaks and resting the ears. Otherwise, there is a danger of increasing the volume to dangerous levels.

How can I make sure my headphone is at a safe level?

• Keep your headset volume as low as possible without straining to hear.
• Co-workers should not be able to hear sounds from your headset.
• With open-air headphones, you should be able to hear normal conversation through the headphones.
• Normal conversation may not be audible with closed-ear headphones. Lift one earpiece off an ear and compare the level in the other earpiece with that of normal conversation to set a safe volume level.

What can I do to prevent hearing loss if I use headphones for my work?

• Set your headphone volume at a conversational level.
• Avoid hearing fatigue. Take a 1-2 minute listening break after working for 30 minutes. A 5-10 minute break is recommended every few hours. After four hours, take a sixty-minute lunch or dinner break, preferably in a quiet environment.
• Reduce ambient noise in your environment. Use curtains and carpeting to reduce indoor noise. Turn off background music and isolate noisy equipment (i.e. printers) by increasing the distance or moving to another room.
• Have your hearing tested during your annual physical

B-12 Deficiency Can Cause Numbness & Tingling in Hands (Among Other Symptoms)  Source http://www.ergoblog.com/

I’m always interested in causes behind symptoms that often get lumped in under “repetitive stress injuries” (RSI).  We blame typing and poor ergonomics for a lot of our woes, but when I was having a lot of trouble with hand pain, it was a matter of changing my diet, not my desk configuration.  Of course, it took a couple doctors before someone thought to have me tested for food allergies (first I had to suffer through the here-take-some-drugs-and-wear-wrist-splints phase followed by the let’s-sign-you-up-for-expensive-physical-therapy-you-can’t-afford phase).  That’s when I found out I was intolerant to gluten and dairy and that eliminating them helped tremendously.

If you’re in the same boat where you’ve tried a lot of the common fixes for hand/wrist/joint pain etc. and haven’t found them all that helpful, it’s definitely worth trying to get to the bottom–figuring out what’s causing the symptoms rather than just trying to treat them.

I was recently surfing around the web and found a list of the common symptoms of vitamin B12 deficiency.  The fact that numbness/tingling in the hands was on the list, of course, caught my eye.  Here’s a list of some of the typical symptoms:

1. Itchy or tingling tongue. The tongue suddenly itches from time to time without warning. This occurs on the edge of the tongue, along one side or the other or at the tip. Some individuals experience stinging, pain, or tingling instead of itching.

2. White spots in the skin, resulting from melanin becoming absent in the area. These often occur on the outside of the forearm, but may occur in other places. The longer these spots are there, the whiter they get. As time goes by, the spots become very dry and flaky to the extent that small raw spots of skin may be exposed.

3. Sharp stabbing, tingling pain in the palm of one or both hands. This occurs suddenly and for no apparent reason in a spot directly below the ring finger, approximately where the first palm crease is. If B12 deficiency is not treated, a tingling pain may begin to occur along the outside edge of the hand, starting from the wrist. This pain occurs when the wrist is extended.

4. Sores at the corners of the mouth, sometimes extending along the edge of the lip. These are raw spots, not blisters, and they tend to come and go.

5. Nerve shock in the side of the body. It can be felt coming on a few seconds before it hits, and then it hits almost like a mild but deep electric shock and quickly subsides. It can occur at the side of either hip or on either side of the upper body, along the ribs. It can occur consecutively in at least two or three locations, one right after the other.

6. Shortness of breath, but without chest pain. This can occur when walking just a few yards.

7. Eye twitch, usually in one eye or the other. It can occur on the eyelid or just below the eye.

8. Facial pain, usually on only one side of the face at a time. This pain varies so much that it would be difficult to describe all the possibilities. This can present as a dull pain in the cheek bone right underneath an eye, or a sharp shooting pain across the forehead, sometimes coming downward from the scalp to the edge of the nose by the eye.

9. Tingling along the back of one or both thighs, starting at the hips and shooting downward.

10. Memory loss and/or disorientation.

11. Migraine headaches. These may be preceded by a temporary blind spot in the center of the field of vision, usually lasting about ten minutes, and sometimes followed by facial pain under the eyes. After the blind spot vanishes, there may be zigzag streaks through the vision that may last up to hours. Even in the same person, there may be extreme variations in the headaches themselves. They may be quite severe with nausea or they may be virtually nonexistent.

This list is from the wikipedia article on Vitamin B12 Deficiency.  I assume not everyone is going to have all of the symptoms (I know I had a couple of the less common gluten intolerance symptoms and few of the common ones when I was tested for that, but eliminating it from my diet was key in getting over my RSI).  Another article on B12 anemia (from WebMD) mentions simply “Numbness or tingling in your fingers and toes.”

If any of this stuff sounds familiar, it’s definitely worth getting a blood test. 

There are several causes of B12 deficiency including simply not eating enough meat (vegans and vegetarians may have the problem and can take a vitamin to overcome it) or not being able to digest it sufficiently (such as may happen with celiac disease or bacteria overgrowth in the intestines). 

Taking vitamin pills may not be that effective if you’re having trouble digesting B12.  Alternatives are B12 shots (which you can give yourself after a doctor shows you how and writes a prescription) or B12 patches which you can buy over the counter.

Fashionable or not, more people are wearing these wireless headsets for making phone calls in the car and in everyday life. This week, I reviewed two that look stylish enough that you won’t mind being seen wearing them: Plantronics Inc.’s Discovery 975 (Plantronics.com) and Aliph’s Jawbone Prime (Jawbone.com).

These Bluetooth headsets cost $130 each and use the best technology from their respective companies, including impressive-sounding features like AudioIQ 2, WindSmart, NoiseAssassin 2.0 and an Acoustic Voice Activity Detector. Each headset aims to deliver clearer incoming and outgoing sound.

After using these two headsets in an office, while walking through noisy city streets and as I drove a car with its windows open, I found that I liked the Plantronics Discovery 975 more than the Jawbone Prime. It felt more comfortable and stable in my ear, and its longer boom fit my face better than the Jawbone Prime’s stubby build. I was able to hear people more clearly while using the Plantronics (PLT) earpiece. But on the other end of the call, friends said the Jawbone Prime did a better job of muffling noise.

The Plantronics Discovery 975 also has something that the Jawbone Prime doesn’t have: a carrying case that holds the earpiece and charges it on the go. This charging case can triple the device’s talk time from five to 15 hours, and it holds its charge for a week on standby. A display on the case shows how much battery remains both in the charged case and on the earpiece itself when it’s held in the case.

Aliph’s Jawbone Prime

I liked using this case because it meant I didn’t have to think so often about charging my headset. It also gave me a place to keep the small Discovery 975 earpiece, making it harder to lose in the bottom of a purse or large work bag. Though people who don’t carry briefcases or purses wouldn’t likely use this case, it’s convenient to have the option.

None of the Jawbone models come with carrying cases, though stores like Best Buy sell some cases that will hold Jawbone headsets. In the future, Aliph says it plans to make its own cases that will hold and charge its Jawbone headsets.

Aliph’s Jawbone has always been one of the most stylish Bluetooth headsets, thanks to its compact form factor and disguised buttons. The Jawbone Prime follows suit with a design that makes it appear slightly smaller than its predecessor. It comes in seven colors, including four especially bright “EarCandy” hues: Drop Me a Lime, Lilac You Mean It, ‘Yello! and Frankly Scarlet. The Prime maintains the original Jawbone’s namesake design feature: If worn properly, it touches your face near your jawbone and removes background noise. But a new feature also uses sound to detect the speaker’s voice and eliminate extraneous noise, so the headset doesn’t always need to touch the face.

The design of the Plantronics Discovery 975 ups the company’s chic factor by replacing its former model’s triangular boom with an elegant boom made of a single thin metallic sliver. It reminded me more of jewelry than a tech gadget. Like the Jawbone models, it looks less geeky because buttons are disguised, and it doesn’t emit a blinking blue light while in use—an improvement for Plantronics. The Discovery 975 comes only in graphite, though AT&T (T) stores will carry it in silver.

I started testing the Plantronics Discovery 975 and Jawbone Prime from my quiet office, without any distracting background noise. There, the Plantronics headset sounded better than the Jawbone, making my voice sound crisper, according to the person on the other end of line; likewise, his voice sounded louder to me. He also said he couldn’t tell I was using a headset while I was on the Discovery 975, but definitely knew I was on a headset while I used the Jawbone Prime.

The Plantronics Discovery 975

Next, I walked along the streets of busy downtown Washington, D.C., chatting on each headset while standing steps away from the squeaky sound of car brakes and taxis honking. Here, the Jawbone did a better job of fading that street noise into the background, compared to the Plantronics headset.

I also took turns using the Jawbone Prime and Plantronics Discovery 975 while driving through the city with all four car windows open to test the antiwind capabilities of each. Here again, the Jawbone Prime sounded better to the person on the other end, though the Plantronics didn’t sound bad. My friend said it would have been impossible to guess where I was while making the phone call using the Jawbone Prime. But from my end of the call, I was able to hear slightly better while using the Plantronics Discover 975.

While using the Jawbone, I accidentally hung up on friends in midconversation a few different times because the place where I pressed to secure the earpiece in my ear was also the Talk button. I tried each of the Jawbone Prime’s three fit earbuds, three round earbuds and its included earloop, but none of these felt as comfortable as the Plantronics headset.

Both headsets are capable of using Multipoint technology, allowing them to connect to two Bluetooth devices at once. They’re each lightweight at .28 ounce and .35 ounce for the Plantronics and Jawbone, respectively; the Plantronics case weighs 1.27 ounces. According to each company, the Plantronics headset takes one-and-a-half hours to fully charge and lasts for five hours of talk time; the Jawbone takes 50 minutes to fully charge and lasts four and a half hours of talk time.

When both headsets were in front of me and I wanted to make a hands-free call, I reached for the Plantronics Discovery 975 because of its overall fit and feel in my ear. It stayed in place using a soft, gel insert that wasn’t uncomfortable, even after long conversations. Its sound quality was good enough for me.
