Abstract
A sound reproduction device such as a radio receiver or a cellular phone includes an antenna, a control unit and a speaker. The control unit determines whether a radio wave receiving condition is satisfactory. The receiving condition is represented by field strength of the radio wave or a degradation of a sound signal in the radio wave. If the receiving condition is not satisfactory, the control unit adds an acoustic effect to the sound signal thereby to notify listeners of degradation of receiving condition. The acoustic effect may be a changing of sound image localization, a changing of a frequency characteristic and a changing of a reverberation characteristic. The acoustic effect is stopped for a specified period after the acoustic effect is added, even when the receiving condition is not satisfactory.
