If two sounds differ in level by 46 decibels what is the ratio of their intensities?
The ratio of intensities between two sounds differing by 46 decibels is 10^4.6, which is approximately 2511.89. This means that the sound with the higher level has an intensity over 2500 times greater than the sound with the lower level.
What level on a sound meter constitutes harmful to your ears?
There is not a set level for everyone. It is recommended that a sound level of 90 decibels not be continued longer than 8 hours. Also, OSHA prohibits exposure to sounds louder than 115 decibels without hearing protection.
How can you differentiate between high and loud sounds and low and soft sounds?
High sounds are usually heard when you play the keys of a piano that are on your right; they have shorter wavelengths than low sounds. Low sounds are usually heard when the keys on a piano's left end are played; they have long wavelengths. Soft sounds are quiet and can't render your ears deaf. Loud sounds that are over 85 decibels can damage your hearing.
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.
What is the volume level of a sound that measures 55 decibels, and how loud is it in comparison to other common sounds?
A sound measuring 55 decibels has a moderate volume level, similar to a quiet conversation or background music. It is louder than a whisper but softer than a normal conversation.
What is the sound level restriction in headphones?
Lower than 90 decibels

How does decibels work?
To calculate the number of decibels that power-level-'A' is greater than power-level-'B',-- Divide 'A' by 'B'-- Take the 'log' of the quotient-- Multiply the 'log' by 10 .If the result is negative, then 'A' is that many decibels lower than 'B'.
Is a normal conversation 80 decibles?
A normal conversation typically ranges from about 60 to 70 decibels, not 80. Sounds at 80 decibels are comparable to heavy traffic or a lawnmower, which is significantly louder than average speech. Prolonged exposure to sounds at or above 85 decibels can potentially lead to hearing damage.

Can dogs detect higher and lower sounds than humans?
yes dogs can detect lower or higher sounds than humans

What common unit is used to measures sound intensity?
Sound is measured in decibels, dB. Ten decibels (one Bel) sounds twice as loud as another sound. One decibel is the amount of sound just distinguishably louder than another sound. Named after A G Bell of telephone fame.
What sounds have a lower frequency than 20hz?
Sounds with a lower frequency than 20 Hz are infrasound, which include natural occurrences like earthquakes and some animal calls. These low-frequency sounds are typically felt more than heard.
How long do you listen to a fire alarm before it causes damage to your hearing?
Prolonged exposure to loud sounds, including fire alarms, can damage hearing. Most fire alarms produce sound levels around 85 decibels or higher, which can lead to hearing damage if exposure lasts for more than 8 hours. However, even shorter exposures to sounds above 100 decibels can cause immediate damage. It's best to evacuate the area promptly to minimize risk to your hearing.
