To enhance the sound on your existing phone without buying a new phone itself, an inline phone amplifier is an add-on product to consider. True to its name, an inline telephone amplifier amplifies the voice on the other end of the phone, allowing you to better hear your callers. Some telephone ringer amplifiers plug into your phone jack (you might need to purchase a two-to-one adapter if you need to plug the phone and amplifier into the same jack), while others connect on one end to your phone base and on the other to your handset—either option is easy to connect without any adjustments needed to your telephone wiring.
What you will need is a traditional corded telephone with a keypad on the base—phone amplifiers typically won’t work on phones that have the dial pad in the handset or on yesteryear’s princess style or trimline model phones.
The first choice to make when picking a model is the level of sound amplification you want. Options vary from about 40 decibels (dB), which is equal to 100 times louder than the normal phone, all the way up to 100 dB and higher.
Next decide on the power source you want. Some phone amplifiers work on electricity with an A/C adapter, others on battery power and a few on both (you have the battery as back-up).
Another great feature to look for is a tone selector for speech clarity; this function makes it easier to distinguish similar sounding words.
In addition to all the sound increases, many telephone amplifiers also have a bright neon or strobe light that flashes when a call comes in to get your attention. For instance, the Amplified Phone Ringer With Strobe Flasher monitors your phone line for incoming calls. When receiving a call, it will alert you with a 120 dB amplified ringer and bright flashing strobe light. The device works with all standard corded phones and it plugs directly into your phone jack.
With a telephone amplifier, you’re sure to never miss a call and to hear your caller better than before.
