Here are some bullet points for your presentation:
- Simultaneous masking occurs when a sound is made inaudible by a noise of the same duration, called a masker.
- The effectiveness of the masker in raising the threshold of the original sound depends on the frequency of the sound and the frequency of the masker.
- The greatest masking occurs when the masker and the sound are at the same frequency, and this effect decreases as the sound frequency moves away from the masker frequency.
- On-frequency masking occurs when the masker and the original sound are within the same auditory filter, making them indistinguishable to the listener.
- Figure 1 illustrates the phenomena of simultaneous masking using a masking tone centered at 410 Hz.
- At low masker levels (around 20 to 40 dB), the masking patterns have little effect on our listening abilities.
- As the masker intensity increases (50 to 80 dB), the masking curves widen, especially for sounds at frequencies higher than the masker.
- Upward-spread of masking is why an interfering sound masks higher frequency signals much more than lower ones.
