The Receiver Measurement Tool for Hearing Aids

If you are worried about your new over-the-counter hearing aids from Soundwave Hearing fitting your ear, don’t be! That is why a receiver measuring tool is included with your hearing aids at no extra cost. You will be able to find the perfect fit for your hearing aid receiver from the comfort of your own home. It is extremely easy. It couldn’t be easier to get started, and we have plenty of how-to videos to help you. All you need is to put the tool over your ear and maybe ask a friend or family member to lend a hand. 

How to Use the Receiver Measurement Tool 

Soundwave Hearing ships all Sontro Self-Fitting OTC Hearing Aids with one size fits most receivers. The receiver should lay flat against the side of your head. Occasionally, however, your ear size may require a longer or shorter receiver. To find the correct size receiver, use the Receiver Measurement Tool. 

Place the tool over the appropriate ear. (See the diagram.) Pick the number that is the closest to the top of the ear canal opening. If you are between numbers, we recommend you choose the higher number. It is ideal to have a friend or family member help you read the number.

OTC Hearing Aids vs. Prescription Hearing Aids

When you go get a pair of prescription hearing aids at a doctor’s office (or another hearing professional), they will measure your ear from the top of the pinna (where your glasses sit normally) to the opening of your ear canal. However, Sontro Self-fitting OTC Hearing Aids completely eliminates this step. Our receiver is one-size-fits-most, and if your ears are not “most,” that is what the receiver measurement tool is for. If necessary, we make it simple for you to exchange it for a larger or smaller size.

How Does the Receiver on a Hearing Aid Work?

A hearing aid receiver is an extremely important part of the hearing aid. The receiver on a hearing aid gathers electrical signals from the amplifier and converts them back into acoustic energy, aka sound. The microphone brings the sound into the hearing aid, which then goes through to the amplifier. Then, the sound goes to the receiver, which transmits the sound to your ear.
