If you are having troubles making out what people are saying on the phone and perhaps you are getting tired of asking people to repeat themselves, you may want to search for an amplifier.Amplifiers for phones can make all the difference for those of you who have hearing loss. Hearing loss came come from many different causes, including aging, injury, or..as in my case..listening to too much loud music (I mean really loud).
Phone amplifiers can range from boosting volume from 25dB to even 40dB, and probably even more, but that is the range that we have available. Some have slide volume controls, and turn on automatically when you pick up the handset.
Some amplifier models are designed to plug into the phone between phone and handset, while yet other products such as the Walker Clarity W1100 Extra Amplified telephone have an amplifier built right in to the phone.
Another use for an amplifier for a phone would be in a noisy place such a machine shop, where you just need a little more volume to be able to hear what the person on the other end is saying.
Make sure when you are searching for just the right amplifier model, you pay particular attention to the listed uses for each. Some models won't work with handsets that have a dialing pad, but other more universal models such as the ClearSounds CLSCSIL40 will work with 99% of phones with its selector switch.
