The majority of hearing aids in use are of this type but a sm
23、all percentage use a bone vibrator instead of an earphone. The use of a bone vibrator requires a different method of measuring the output from the hearing aid and also makes it impractical to measure amplification directly in terms of acoustic gain. Amplification in the case of an air conduction hea
24、ring aid is expressed as the difference between the output sound pressure level in an acoustic coupler or ear simulator and the input sound pressure level measured in a specified manner. However, with bone conduction hearing aids the input is in terms of sound pressure level but the output will be i
