Sonic Trek and power behind-the-ear hearing aids

What do SP and UP mean?

The Sonic Trek family has two behind-the-ear options: super power (SP) and ultra power (UP). These abbreviations describe how much the hearing aid can amplify sound. Power hearing aids are considered for hearing losses that need more amplification to make sound audible. Our hearing specialist decides which power is needed based on the results of your hearing test.

Why the ear mould matters

In power behind-the-ear hearing aids, sound travels from the housing through a tube to a custom ear mould. It is important that the mould fits the ear well. If sound leaks out around the edge of the mould, it returns to the microphone and whistling (feedback) can occur. For this reason, the mould is made from an impression of your ear. As the shape of the ear can change over time or the mould can wear, the mould may need to be renewed at intervals.

Daily use and care

• Wipe the mould with a dry cloth every day and check the sound opening for wax.
• If the mould needs washing, detach it from the housing and refit it only once it is completely dry.
• If the tube hardens or cracks, come to us to have it renewed.
• At night, keep the hearing aid in a dry case, away from water and heat.

Trial and follow-up

After the hearing aid is fitted, the volume is usually set over several appointments rather than all at once. This way you get used to powerful sound step by step. During the trial, note your experiences with television, the phone and family conversations. At follow-up appointments, we adjust the programs based on these notes. If you notice a change in your hearing, let us know without waiting for your check-up.
