Abstract

PURPOSE: To sensuously equalize visual sound change to aural sense by displaying large sound volume and low sound volume with the grade step of even times of the intermediate sound volume.
CONSTITUTION: Binary input signals 41W44 are controlled in sound volume level by a sound volume level control circuit 45 and decoded by a decoder 1 to produce signals 2W17 of sixteen grades. Low and high sound volume outputs 2W7 and 12W 17 are connected by two sets through OR gates to display units 48W50 and 55W57. The low and high sound volume level display units 48W50 and 55W57 display sound volume level by 10dB step and the intermediate level display units 51W54 display sound volume level by 5dB step.
