SHS 311 EXAM QUESTIONS WITH 100% CORRECT ANSWERS What are the three types of temporal masking? - Answer- 1. Simultaneous masking 2. Forward masking 3. Backward masking What is simultaneous masking? - Answer- Noise and masker overlap at the same time Ex. Having a conversation with someone in a room (convo of about 65 dB) and hearing a radio in the room as loud as a concert (about 120 dB) - You no longer can hear the other person talking because you are completely masked out What is f...
