What types of sounds are usually the first to decline with hearing loss?

When a decline in hearing does happen, the first thing to go is the ability to clearly hear high-pitched sounds such as women’s and children’s voices, especially in situations where there’s considerable background noise.

How does low frequency sound affect hearing?

At very low frequencies (less than 250 Hz), however, the sensitivity of human hearing, and therefore the perceived loudness is poor. The perceived loudness is mediated by the inner hair cells of the cochlea which are driven very inadequately at low frequencies.

Why are lower frequencies easier to hear?

Why is some sound easier to hear than others? Low frequency sounds lose less energy as they pass through a solid object. This is for two reasons; their longer wavelength, and the fact that low frequency sounds create resonance/vibration in walls and this helps propagate the passage of sound.

What frequency of hearing is lost first?

As hearing loss progresses, the rate of hearing loss decreases. Loss is always greater at the frequencies 3000-6000 Hz than at 500-2000 Hz. Loss is usually greatest at 4000 Hz.

Is low frequency sound is faint?

Low frequency sound is faint while high frequency sound is loud.

What does low frequency sound do?

Low frequency noise, considered as the frequency range from about 10Hz to 200Hz, causes extreme distress to a number of people who are sensitive to its effects. The sensitivity may be a result of heightened sensory response, within the whole or part of the auditory range, or may be acquired.

Does hearing loss begin with higher or lower frequencies?

If the sensory cells in your cochlea are damaged, you lose the ability to hear and ultimately process these sounds. As the hair cells that perceive low-frequency sounds are located near the top of the cochlea, hearing loss typically occurs at higher frequencies first.
