How many time more is the orchestra than the soloist if the orchestra has a sound intensity of 90 db and the soloist has a sound intensity of 70 db?

(90 dB - 70 dB) = 20 dB = 100 times as much sound power.(100 times 'as much' = 99 times 'more')


A sound of 20 dB intensity is twice as loud as one of 10dB?

No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10.

How does intensity of a 40 decibel sound compare to intensity if a 20 decibel sound?

The 40dB sound is (40 - 20) = 20 dB louder than the 20 dB sound.20 dB louder = 10(20/10) = 102 = 100 times louder

How many times louder is 100 dB that 10 dB?

A 10 dB sound pressure level (SPL) is 0.000063 pascal and 100 dB is 2 pascal. Loudness is a problematic psycho acoustic feeling. I don't know what three times louder really means.

What is OSHA's noise limit?

Effectively, OSHA has two noise limits that apply simultaneously. First, employees may not be exposed to a full-shift (8-hour) time-weighted average noise level of 90 dB (deciBells) or more. This translates to a limit of: 90 dB averaged over an 8 hour day, or 95 dB for 4-hours as long as the rest of the day does not involve exposure to noise greater than 90 dB, or 100 dB for 2 hours, 105 dB for 1-hour, 110 dB for 30 minutes, 115 dB for 15 minutes, and no continuous noise louder than 115 dB In addition, employees who have 8-hour exposures of 85 dB or more must be placed in a Hearing Conservation Program and, in some cases must be provided with hearing protection. The table is a bit different because sounds from 80 dB and above are used in the assessment. This translates to a criterion level of: 85 dB averaged over an 8-hour day, or 90 dB for 4-hours for 4-hours as long as the rest of the day does not involve exposure to noise greater than 80 dB, or 95 dB for 2 hours, 100 dB for 1 hour, 105 dB for 30 minutes, 110 dB for 15 minutes
