Description:The first oscillator, the "masking" tone, is set to a 500 Hz sine wave at medium intensity. The second is to be the "masked" tone, which will be varied in frequency and in intensity. The second tone is easily masked when its frequency is higher and its amplitude lower than the masking tone. Masking occurs very readily when the second tone is up one octave, twice the frequency of the masking tone. Frequencies below the masking tone are not easily masked, even at relatively low amplitudes.
Masking phenomena are significant in understanding the process of hearing. When analyzing a complex sound, it is notable that masked components can be altered or removed without substantially changing the experience of hearing.
