What are jobs where a person would need a good sense of hearing?

Hearing damage

Damage to the cochlea’s hair receptor cells can cause hearing loss. Hair cells have been compared to carpet fibers. Walk on the carpet and the fibers will spring back after vacuuming, put a heavy piece of furniture on them and they never rebound. Based on what we know about hearing loss, can teenagers damage their hearing by listening to music too loud? Explain.

The normal human ear can hear sounds from 50Hz to 20KHz, for dogs it mostly depends on their breed and age but they can hear 40 Hz to 60,000Hz. Mice hear higher frequencies than humans, their range is 1KHz to to 70KHz.

-frequency theory enables us to hear low pitches (20-300 hz)
-place theory enables us to hear high pitches (5,000-20,00hz)
-volley theory enables us to hear mid-range pitches (300-5,000 hz)

The Frequency theory is the best at perceiving perception at 20 and 1,00 cycles per second, it notes that for us to percieve lower pitches we need to match the frequency of the sound waves with our neural impulses.

-A major point with Frequency theory, is that the frequency analysis is carried out in the inner ear creating a neural spectrogram that is transmitted to the brain
- A major point with place theory is that frequency analysis is not carried out in the inner ear, but that a time domain representation is transmitted to the brain and the frequency analysis is carried out in the brain.
- Could help give an explnation of the hearing going on in the middle. It does not explain

Children and young adults ears can hear from 50 HZ to 20 HZ. While a Bat (who requires very sensitive hearing) to make up for the lack of sit. There hearing range is between 20 HZ and 120,000 HZ. Mice have large ears this makes there frequency range 1kHz to 70 kHz or 90. They can not hear lower frequencies. Humans do not compare well to these animals.

Frequency theory is the better of the three. It makes sense that they would be a made neural spectrogram to transmit to the brain.

Audio Engineer- These people are able to pick out subtle tones and make them into something greater.

Conductor- They're able to perceive tone and pitch in a way most can't

Air Traffic controller- A controller needs to be able to coordinate all that traffic on a schedule
