How Loudness Differs With The Person?

What is the loudest thing?

Krakatoa is believed to be the loudest sound produced on the surface of the planet — in human history, that is.

It circled the Earth four times in every direction and shattered the ears of sailors 40 miles away.

The Krakatoa volcano erupted with ungodly strength, sending ripples of sound heard thousands of miles away..

Can a sperm whale kill you with sound?

Sperm Whales Are So Loud They Could Potentially “Vibrate” You to Death. Sperm whales are so loud that their clicks are capable of killing a human within their vicinity, says one science and adventure journalist. … Sperm whales are the loudest mammals on the planet, with vocalizations reaching an astonishing 230 decibels.

What is the loudest frequency?

Loudness and pitch For a person with normal hearing, when it comes to pitch the human hearing range starts low at about 20 Hz. That’s about the same as the lowest pedal on a pipe organ. On the other side of the human hearing range, the highest possible frequency heard without discomfort is 20,000Hz.

How does loudness work?

The loudness control is simply intended to significantly boost low and high frequencies when listening at low levels so that the ear perceives an overall flatter sound pressure level. In other words, if the loudness contouring control is not enabled at low volume levels, bass and treble appear to be lacking.

What is the loudness of sound called?

The loudness of a sound is called. the sound wave. the volume.

How do humans perceive loudness?

Explanation. The perception of loudness is related to sound pressure level (SPL), frequency content and duration of a sound. … The sensitivity of the human ear changes as a function of frequency, as shown in the equal-loudness graph.

What frequency can kill you?

The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.

How loudness of sound varies with the person?

The loudness of sound as perceived by human ears is roughly proportional to the logarithm of sound intensity: when the intensity is very small, the sound is not audible; when it is too great, it becomes painful and dangerous to the ear. … This range varies from person to person and with the frequency of the sound.

What noises are 60 decibels?

A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB.

How loud is 1000hz?

Using the 1000 Hz sound as a standard, for example, if you look at the 40 phon line*2, the sound pressure of 1000 Hz is 40 dB, but you can tell it’s 60 dB for 125 Hz, and 73 dB for 63 Hz.

Why is loudness called volume?

The word “volume” refers to how much space a three-dimensional object takes up. The word is commonly used to define the magnitude or loudness / intensity of sound. The louder a sound, the more energy it has. This means loud sounds have a large amplitude.

As you know, we are not equally sensitive to sounds of all frequencies so perceived loudness of a tone in fact depends on frequency as well as intensity. Two sounds can have the same physical sound pressure levels but if they are of different frequencies, they are often perceived as having different loudness.

What does loudness depend on?

Solution: The loudness of a sound depends on the amplitude of vibration producing the sound.

What is the intensity of sound of 70 decibel?

How do you calculate loudness level?

The curve for loudness level can be seen below:The loudness level is measured in phons. LL in phons = SL in db L in phons = 2^((LL-40)/10) … 3-4: 1 SEE ANSWER.

Can loud sound kill you?

The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. … High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.

The intensity of a sound is the power of the sound in Watts divided by the area the sound covers in square meters. The loudness of a sound relates the intensity of any given sound to the intensity at the threshold of hearing. It is measured in decibels (dB).
