That tells it all:
"Permitted Noise 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.
What else can I help you with?
How loud does a sound have to be to cause damage to the ears?
Sounds above 85 decibels can cause hearing damage with prolonged exposure. The higher the decibel level and the longer the exposure, the greater the risk of hearing damage. Sounds above 120 decibels can cause immediate harm.
What is the maximum sound level in decibels that can cause permanent hearing damage, with 230 dB being the threshold?
The maximum sound level that can cause permanent hearing damage is around 130 decibels. Sound levels above 130 decibels can lead to hearing loss.
Is 92 decibels damaging to hearing?
Yes, prolonged exposure to 92 decibels can cause hearing damage. It is recommended not to be exposed to noise levels above 85 decibels for an extended period of time without ear protection to prevent hearing loss.
How loud sound can extremely make you deaf?
Sounds over 85 decibels can cause hearing damage, with prolonged exposure increasing the risk of permanent hearing loss. Sounds over 120 decibels, such as explosions or jet engines, can cause immediate and severe damage to the hearing system.
What is the maximum level of sound intensity, measured in decibels, that can cause permanent hearing damage, such as 1100 dB sound?
The maximum level of sound intensity that can cause permanent hearing damage is around 120-130 decibels. Sound intensity of 1100 dB is extremely high and would cause immediate and severe damage to hearing.
What sound level damages your hearing?
Continuous exposure to sounds above 85 decibels can cause hearing damage over time. Sounds at 120 decibels or above, such as a rock concert or a gunshot, can cause immediate hearing damage. It's important to protect your ears from loud noises to prevent permanent hearing loss.
How many decibels is a large cannon?
A large cannon can produce around 175-185 decibels. This is extremely loud and can cause hearing damage if not properly protected.
Can noise greater than decibels cause loss of hearing?
It depends on the time you are listening. It starts with 85 dBSPL longtime listening. 120 dB short time listenenig gives you a headache and ringing in your ears.
What is the relative intensity of 130 decibels?
At 130 decibels, the relative intensity would be very high. It is considered to be extremely loud and can cause immediate damage to hearing. Exposure to sound at this intensity level for prolonged periods can lead to hearing loss.
What is the maximum sound level in decibels that can cause permanent hearing damage, with 1100 dB being the threshold?
The maximum sound level that can cause permanent hearing damage is around 85-90 decibels. Sounds above this level, especially prolonged exposure, can lead to hearing loss. The threshold for permanent damage is much lower than 1100 dB.
Can sound greater then 120 decibels cause pain to humans?
ya it can hurt someones ears
What decibel is deafening?
Starting at 85 decibels, ear plugsshould be worn because hearing damage begins. At 140 decibels, no matter what the frequency or duration of time, serious damage is inflicted to the ears and it is extremely painful. At 145 decibels, vision begins to blur due to vibration. 163 decibels is the minimum glass breaking sound level.Go to this chart for a more detailed explanation.http://makeitlouder.com/Decibel%20Level%20Chart.txt
