| Summary, etc | This chapter reviews the general types of signal processing that are used<br/>in modern digital hearing aids. The focus is on concepts underlying the processing<br/>rather than on details of the implementation. The signal processing can be classified<br/>into three broad classes: (1) Processing to apply frequency- and level-dependent<br/>amplification to restore audibility and provide acceptable loudness, based on the<br/>hearing profile of the individual (usually the audiogram but sometimes taking into<br/>account the results of loudness scaling) and the preferences of the individual.<br/>Frequency lowering can be considered as an additional method for restoring the<br/>audibility of high-frequency sounds. (2) Sound cleaning, for example, partial<br/>removal of stationary noises or impulse sounds and reduction of acoustic feedback.<br/>Noise reduction may be achieved using both single-microphone and multiplemicrophone<br/>algorithms, but only the latter have been shown to improve intelligibility.<br/>(3) Environment classification for automatically controlling the settings of a<br/>hearing aid in different listening situations. It is concluded that modern hearing aids<br/>can be effective in restoring audibility and providing acceptable loudness and listening<br/>comfort, but they are still of limited effectiveness in improving the intelligibility<br/>of speech in noisy situations. |
