A、Low-pitched sounds have a significant masking effect on high-pitched sounds
B、The closer the frequencies of the sound and the masked sound are, the greater the masking effect will be
C、High-pitched sounds have only a small masking effect on low-pitched sounds
D、Increasing the sound pressure level of masking sound is helpful to reduce the masking effect
喵查答案：Increasing the sound pressure level of masking sound is helpful to reduce the masking effect
Which is incorrect among the following statements about the “masking effect”?
-
Generally speaking, the higher the sound quality is required, the higher the quantization level and the lower the sampling frequency is. -
The higher the sampling frequency, the closer the discrete digitized sound wave is to its original waveform. -
Audio files in WAV format do not use compression algorithm, so they have good sound restorability, strong stereoscopic impression and relatively large file capacity. -
MPEG video compression standards include MPEG-1, MPEG-2, MPEG-4, MPEG-7 and MPEG-21.
