Sound is a form of energy that travels through the air or any other medium in the form of waves. Humans have the ability to hear sound waves that fall within a certain range of frequencies. The audible sound range for humans is measured in decibels (dB).
What Is A Decibel?
A decibel is a unit that measures the intensity of sound. It is a logarithmic scale of measurement that compares the sound pressure level of a particular sound to the reference sound pressure level. The reference sound pressure level is the lowest sound level that a human ear can hear, which is 0 dB.
The Audible Sound Range For Humans
The audible sound range for humans is between 0 dB and 140 dB. Any sound that falls within this range can be heard by the human ear. However, sounds that are too loud can cause damage to the ear and even lead to hearing loss.
Sounds Within The Audible Range
Sounds that fall within the audible range include the sound of a whisper, which is around 30 dB, the sound of a normal conversation, which is around 60 dB, and the sound of a rock concert, which can reach up to 120 dB.
What Happens When Sound Reaches 140 dB?
When sound reaches 140 dB, it is considered the threshold of pain. At this level, the sound can cause physical pain and even damage to the ear. Examples of sounds that can reach 140 dB include a jet engine at takeoff and a gunshot.
How To Protect Your Ears From Loud Sounds
To protect your ears from loud sounds, it is important to wear earplugs or earmuffs when exposed to loud noises. You should also limit your exposure to loud sounds and give your ears a break from time to time.
The Importance Of Protecting Your Ears
Hearing loss is a common problem among adults, and it is often caused by exposure to loud sounds over a long period of time. By protecting your ears from loud sounds, you can prevent hearing loss and maintain your ability to hear throughout your life.
The Bottom Line
The audible sound range for humans is between 0 dB and 140 dB. Sounds that are too loud can cause damage to the ear and lead to hearing loss. To protect your ears, it is important to wear earplugs or earmuffs when exposed to loud noises and limit your exposure to loud sounds.
