The ear drums are moved by the sound pressure deviations only. Therefore don't ask for sound intensity.
Sound pressure is measured by an SPL meter. Very loud noise is aching. The "threshold of pain" has the value of about 130 dB Sound Pressure Level (SPL).
"Permitted Exposure Time Guidelines - SPL"
Sound pressure level Lp and permissible exposure time t:
115 dB = 0.46875 minutes (~30 sec)
112 dB = 0.9375 minutes (~1 min)
109 dB = 1.875 minutes (< 2 min)
106 dB = 3.75 minutes (< 4 min)
103 dB = 7.5 minutes
100 dB = 15 minutes
97 dB = 30 minutes
94 dB = 1 hour
91 dB = 2 hours
88 dB = 4 hours
85 dB = 8 hours
82 dB = 16 hours
Lower dBs are said to be harmless
There are accepted standards for recommended permissible exposure time for continuous time weighted average noise, according to NIOSH (National Institute for Occupational Safety and Health) and CDC (Centers for Disease Control and Prevention) in 2002.
For every 3 dBs over 85 dB, the permissible exposure time before possible damage can occur is cut in half.
What else can I help you with?
What is the faintest sound people can hear in decibles?
The faintest sound people can generally hear is around 0 decibels. This is the threshold of hearing, also known as the absolute threshold of hearing, and represents the lowest intensity sound that can be detected by the human ear.
What is the relationship between the intensity of sound waves and their effect on human hearing?
The intensity of sound waves is directly related to their effect on human hearing. Higher intensity sound waves can cause damage to the delicate structures in the ear, leading to hearing loss or other auditory issues. Lower intensity sound waves are less likely to cause harm to the ear.
How many decibels correspond to the lowest intensity sound you can hear?
He found that even the most complex periodic wave motion can be disassembles into simple sine waves that add together.
What is a measure of the loudness or intensity of sound?
The measure of the loudness or intensity of sound is called decibels (dB). It quantifies the level of sound pressure that is perceived by the human ear. The higher the decibel level, the louder the sound.
The intensity of sound depends on what?
The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity. Our ears and the microphone diaphragms are moved by the sound pressure variations.
How does intensity affects how you hear?
It's not the sound intensity I (acoustic intensity) as sound power quantity, it's the sound pressure p as sound field quantity, which moves you ear drums. I ~ p²
How do you hear sound through the ear?
when you hear things, its really sound waves. the sound waves enter your ear, then it vibrates the ear drum.
How can you hear a sound?
with your ear
What is the maximum sound level is safe for human ear in DB?
What is the maximum sound level is safe for human ear
What is the human perception of intensity?
Our ear drums with the ear/brain system are moved only by sound pressure motions. The sound pressure is the effect, but the sound power (sound intensity) of the source is the cause.
What is the faintest sound people can hear in decibles?
The faintest sound people can generally hear is around 0 decibels. This is the threshold of hearing, also known as the absolute threshold of hearing, and represents the lowest intensity sound that can be detected by the human ear.
What is a use of ear?
It is to hear sound
Human ear can hear minimum and maximum?

Why does cupping your hand around your ear make a sound louder?
Cupping your hand around your ear helps to collect and channel sound waves towards your ear, increasing the intensity of the sound that reaches your eardrum. This amplifies the sound and allows you to hear it more easily.
If there is a tree that falls in the woods and no one is there to hear it does it make a sound?
no because sound is thecnacly the vibrations in your ear so no ear no sound
What happens in between where the sound begins and your ear to allow you to hear the sound?
it creates gaps in the air and then goes to your ear
What sense organ helps you hear sound?
The ear
