Check the hearing aid memory environment(s). If patients are streaming in “television” environment, it will sound “tinny”. Changing to “normal” environment reduces the “tinny” audio quality. Just because patient is streaming from a TV does not mean they should use a “television” environment in their hearing aids.

Open fittings will sound more “tinny,” than more occluded fittings.
Increasing low frequency gain (200, 500, 1000 Hz) to “normal” environment adds “fullness” to audio quality. More occlusion yields more noticeable results.
| Note: “Tinny” typically indicates too many high frequencies (or not enough low frequencies). If it is an open-fit hearing aid, then some low frequencies may be programmed out of the hearing aid response via the fitting software. It is assumed that some of these low frequencies arrive through the open ear-canal naturally. When streaming, there is not much low frequency gain applied to the streamed signal. To increase low frequency performance, the professional can add a special “Streaming” memory with more low frequency amplification. Adding a memory designed for streaming may resolve the complaint. |
