The exact distance a human ear can hear depends on many different factors, such as the level of background noise and the frequency of the sound being heard. Generally speaking, however, a human ear can detect sound from up to around 400 feet away in quiet environments, or from up to around 30 feet away in noisy environments.
In addition, the human ear can pick up sound waves with frequencies as low as 20 Hertz (Hz) and as high as 20,000 Hz. When sound waves are present at very high decibel (dB) levels, a person can hear them from greater distances than normal.
For example, if a person is exposed to a sound at 130 dB, they can typically hear it from up to around 10 miles away.
Can you hear from a mile away?
No, it is not possible to hear from a mile away. Sound travels through air and the air around us absorbs sound, making it difficult to hear from distances any farther than a few hundred feet away. Even in very open areas with no obstructions, sounds will dissipate and become dissipated over such long distances, making it practically impossible to hear from a mile away.
Additionally, wind and other environmental factors can further reduce the sound’s ability to carry far.
Can normal human ear detect sounds ranging between 0 150 dB 0 140 dB 0 120 dB 0 100 dB?
Generally speaking, yes, the normal human ear can detect sounds ranging from 0 to 150 dB. The range of what the human ear can detect actually varies from person to person, as some people may have better hearing than others.
Generally, however, the range for what the human ear can detect normally lies between 0 to 140 dB, with some people being able to detect as low as 0 dB and as high as 150 dB. Even within this range, certain frequencies will be better heard than others.
For example, a sound at 120 dB may be heard more easily than a sound at 100 dB, so the range of what an average person can detect will differ with respect to frequency.
What dB is considered deaf?
Answer: The World Health Organization (WHO) considers a hearing loss to be severe when it is greater than 70 dB (decibels) in the better hearing ear. Hearing loss greater than 91 dB is considered profound, and any hearing loss greater than 91 dB is considered to be deafness.
To put these numbers into perspective, an average conversation occurs at 60 dB, while a whisper is around 30 dB.
How many dB does it take to go deaf?
It is impossible to say precisely how many decibels it takes to go deaf since everyone’s hearing is unique and different levels of sound exposure can result in hearing loss with varying severity. Studies have found that prolonged exposure to any sound over 85 decibels can cause hearing damage, and the loss becomes more pronounced the longer the exposure and the higher the decibel level.
For example, long-term exposure to a sound at 120 decibels or higher can cause permanent hearing loss, while it might take a sound of 140 decibels to result in more severe hearing loss for a shorter duration.
Noise-induced hearing loss can also vary depending on factors such as age, genetics, and the duration and frequency of exposure to the sound. Additionally, some people can become deaf even from lower decibel levels if their exposure is long enough, while others may not experience any hearing loss at high decibel levels for short periods of time.
