What is 140 decibels equivelent to?
140 decibels is equivalent to the sound level of a jet engine at takeoff or a gunshot at close range. It is considered extremely loud and can cause immediate hearing damage or pain to unprotected ears. For context, normal conversation is about 60 decibels, while sounds above 85 decibels can be harmful over prolonged exposure.
How loud is 62 db?
A sound level of 62 decibels (dB) is comparable to the noise of a normal conversation or background music in a restaurant. It is generally considered to be moderately loud but not disruptive. For context, normal breathing is around 10 dB, while a quiet library might be around 40 dB. Sounds above 60 dB can start to become intrusive, especially in quiet environments.
What is next number in sequence 60-30-20-15-12?
Those are the factors of the number 60, in descending order. The next factor is 10.

What should the next number be 20 30 40 50 60 70?
The next number should be 80.
Compared to a sound of 40 decibels a sound of 60 decibels is?
Twice as loud. Decibels are measured on a logarithmic scale, so an increase of 20 decibels represents a tenfold increase in intensity.
What is half as loud in db?
Half as loud in decibels is about a 10 dB decrease. For example, if a sound is initially at 70 dB, half as loud would be around 60 dB.
Which is louder 60 or 70 decibels?
40 dB gain change should give about the ratio of 16 for sensed volume and loudness, 40 dB gain change gives the ratio of 100 for measured voltage and sound pressure and 40 dB gain change gives the ratio of 1000 for calculated sound power and acoustic intensity. Go to the link: Subjectively perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power).
What is the decibel level of an average rooster's crow?
An average rooster's crow is approximately 90 decibels. This is about as loud as a dog barking. Chickens themselves average 60-70 decibels, which is on par with human conversation.
How loud is 60 65 70 decibels in relations to everyday sounds?
The range of 60-70 decibels sound pressure level is about as loud as normal conversation in 1 meter distance. The distance from the ears to the sound source is very important to the value of the SPL. Scroll down to related links and look at "Table of Sound Pressure Levels". Decibel Table - Comparison Chart - Table of Sound Levels and corresponding Sound Pressure and Sound Intensity - Units and Quantities.

What is optimum sound level for human being is?
The optimum sound level for a human being is around 60-70 decibels for regular conversation and activities. Prolonged exposure to sounds above 85 decibels can be damaging to hearing. It is important to protect your ears from loud noises to prevent hearing loss.
