Clinical experiments with hearing aids with amplitude compression.
The model for audiological rehabilitation in Denmark is brief-described. Clinical experiments have not demonstrated a general superiority of the compression hearing aids compared to the conventional hearing aids. In situations with negligible background noise the compression hearing aid tends  to provide the best comprehension of speech. However, in situations with background noise the conventional hearing aid is generally preferred by hearing impaired persons. The attitude with regard to compression hearing aids differs among Danish hearing clinics. One clinic with a very positive attitude delivers compression hearing aids to 27% of the total clientele. In several clinics it has been observed that patients with a perceptive impairment who are using the hearing aid for the first time may benefit from compression during the early stages of hearing aid adjustment. In many cases, however, these patients prefer less compression as they continue to use their hearing aids in daily life. It is pointed out, that in connection with compression hearing aids it is especially important to provide careful instruction about the possibilities and limitations of the hearing aid.
