Observations and results: Your results may vary, but you likely found that the Mosquito sound was detected less frequently by older volunteers. Volunteers in their early 20s should have been able to hear the sound.

Volunteers in their teens and child volunteers should have been able to hear the sound easily. One kHz is equal to 1, Hz. The average adult is able to hear sounds between 0.

The Mosquito sound has a frequency of No wonder—the sound wave produced by the recording you listened to compresses and stretches the air at a rate of 17, times per second.

The older age group likely had trouble hearing the Mosquito because as we age, our ability to hear high-pitched frequencies wanes. This process is called presbycusis, the onset of which is sometimes observable in people as young as Presbycusis is very different than noise - induced hearing loss, which happens as a result of acute or sustained exposure to very loud noises.

The body responds by sending oxygen to this region of the ear, leading to oxidative cell death. Curiously, noise-induced hearing loss usually makes it harder to hear lower frequencies, such as those between three kHz and six kHz, whereas presbycusis gradually erodes our ability to hear higher frequency sounds in general. Presbycusis is unavoidable, but you can take steps to avoid noise-induced hearing loss, like wearing earplugs to concerts and keeping the volume of your headphones at a reasonable level.

This means they have trouble hearing the voices of women and young children as well as s, h or f sounds.

Amplitude is the measurement of how forceful a wave is. Measured in decibels dB , the louder the sound is, the higher the decibel number will be. Normal conversations are measured at about 65 dB.

Frequency is the measurement of the number of sound vibrations in one second. Measured in hertz Hz , a healthy ear can hear a wide range of frequencies, from very low 20 Hz to very high 20, Hz. As we age, so do our inner ears. Because of this, there are certain sounds that we simply cannot hear as we get older.
