# One What is the shortest wavelength you can hear?

• Tuxedo
In summary, the shortest wavelength that is audible to humans is about 20-40Hz. This is likely due to the use of resonant sensors in a special device that isolates and amplifies human voice signals while blocking out other sounds, such as a noisy jackhammer. The device operates on the principle that lower frequency sounds have longer wavelengths, making them easier to detect and transmit.

One What is the shortest wavelength you can hear?
TwoA special device can transmit out-of-phase sound from a noisy jackhammer to earphones worn by its operator. Over the noise of the jackhammer, the operator can easily hear your voice while you are unable to hear his, Explain.

The shortest wavelenghth you can hear is about 20-40Hz.

Probably the device has some resonant sensors, that only respond to the wavelength of human voice (the jackhammer's sounds should have lower wavelengths). The device also isolates the all the sound around and only the signals received by the sensors are amplified and led to his ears

No. That's the longest wavelength.

EDIT: I took out the rest of the answer because this is obviously homework. What realtion do you know between frequency and wavelength?

Sorry guys for wasting your time I solved it

## 1. What is the shortest wavelength that humans can hear?

The shortest wavelength that humans can hear is around 20 Hz, which corresponds to a wavelength of 17 meters.

## 2. Can humans hear wavelengths shorter than 20 Hz?

No, humans cannot hear wavelengths shorter than 20 Hz. These wavelengths are known as infrasonic waves and are below the audible range for humans.

## 3. How do animals with higher or lower hearing ranges compare in terms of shortest wavelength they can hear?

Animals with a higher hearing range, such as bats and dolphins, can hear much shorter wavelengths than humans. On the other hand, animals with a lower hearing range, such as elephants and whales, can only hear longer wavelengths than humans.

## 4. Is it possible for humans to artificially hear wavelengths shorter than 20 Hz?

Yes, it is possible for humans to artificially hear wavelengths shorter than 20 Hz through the use of specialized equipment, such as ultrasonic microphones. However, these sounds may not be perceived as audible to the human ear.

## 5. Can exposure to extremely short wavelengths damage human hearing?

Yes, exposure to extremely short wavelengths, such as those in the ultrasonic range, can potentially damage human hearing. It is important to limit exposure to these wavelengths to prevent potential harm.
