[Problem] In conventional measurement/analysis using a standard curve, it is necessary to convert the measurement output by using a standard curve. Also, in conventional sound effect adjustment, as a result of performing control in terms of sound pressure level units, in order to directly employ the detected electrical signal as a control signal, adjustment must be performed using for example a filter or equaliser. [Solution] By adding an "inverse characteristic filter" and "unit conversion calculation" to the functional layout of a typical measurement method, in for example measurement of hearing level, the measurement results can be output in standard curve units such as hearing level, or, in measurement of NC level, can be output in standard curve units such as NC level, and/or sound effect adjustment can be controlled in terms of hearing level. |
