Measurement of characteristics of bone conduction hearing aids is usually made by using an artificial mastoid. Therefore in the characteristics of a bone conduction hearing aids, there are nothing stated about the sound which can be perceived only through the bone conduction of mechanical vibrations. As a new appraisement, an equivalent sound pressure level related to vibrations on the mastoid is formulated and the process of getting an equivalent sound pressur level is described. Equivalent sound pressure levels for 1 g accerelation applied to a forehead are also measured instead of measuring threshold levels.
