If a human being is exposed to a sound at 50,000 Hz at 180 decibels, what will happen?

a. The sound will cause massive damage, resulting in immediate hearing loss.

b. The person will have hearing loss but only at the presented frequency.

c The sound will cause a paradoxical response, and the person will hear a low tone instead of a high tone.

d.The person will hear nothing because the sound is above the human range of frequency.

When you play piano, why might you have to hit the keys harder with your left hand (lower notes) than your right hand (higher notes) to make them sound the same volume?

a. Lower-frequency tones require higher dB levels to sound the same volume as higher-frequency tones.

b. The audibility threshold curve is lower for low-frequency sounds and higher for high-frequency sounds.

c. Low-frequency sounds are more condensed, making them sound louder.

d. High-frequency sounds are less condensed, making them sound softer.

e. Higher-frequency tones require higher dB levels to sound the same volume as lower-frequency tones.

a. Lower-frequency tones require higher dB levels to sound the same volume as higher-frequency tones.

Why is white noise the best choice for masking random sounds in an environment?

a. Since white noise includes energy at all frequencies, it is good at masking random sounds of any frequency.

b. White noise consists mostly of low frequencies, which are the best at masking random sounds since they also tend to be mostly low frequencies.

c. The structured and cyclical nature of white noise provides a clear pattern that interferes with the perception of random sounds in the environment.

d. White noise consists mostly of high frequencies, which are the best at masking random sounds since they also tend to be mostly high frequencies.

e. White noise consists mostly of medium frequencies, which are the best at masking random sounds since they also tend to be mostly medium frequencies..

a. Since white noise includes energy at all frequencies, it is good at masking random sounds of any frequency.
