What is the decibel of a whisper?
About 20 dB SPL (sound pressure level).
Compared to a close whisper at 20 dB. How many times more intense is a normal conversation at 60 dB?
10,000
How much more intense is a close whisper than the threshold of hearing?
According to study closer whisper is about 100 times more intense than the threshold of hearing.
What sound level damages your hearing?
90 db
If one lawn mower causes an 80 dB sound level at a nearby point what sound level at that point would four lawnmowers together cause?
84 dB at that point
What is the decibel of a whisper?
About 20 dB SPL (sound pressure level).
How loud is 69 db?
Since the db scale is relative, it depends on what 0 db means. Typically, however, 69 db is a very soft sound, almost a whisper.
Compared to a close whisper at 20 dB. How many times more intense is a normal conversation at 60 dB?
10,000
What is the difference between dB HL and dB SPL?
dB HL stands for decibel Hearing Level, and dB SPL stands for decibel Sound Pressure Level.
How much more intense is a close whisper than the threshold of hearing?
According to study closer whisper is about 100 times more intense than the threshold of hearing.
How loud is 60 db?
60 dB sound pressure level is about conversational speech listened in 1 meter distance.
What does sensation level mean?
The sensation level is measured in decibels. It is frequency specific and starts at 0 dB SL (sensation level) where 0 dB SL is the softest the patient can here a specific frequency. This means that the SL will be different for different people. Everyone's SL will start at 0 but my SL at 1000 Hz may be at 23 db IL and another's may be at 54 db IL.Put more simply, dB SL is the difference between a person's threshold of hearing and the presentation level of a stimulus. If a person's speech reception threshold (SRT) is 10 dB on an audiometer (dB HL) and you present a speech stimulus to them at 50 dB HL on the audiometer, their sensation level would be derived thus: 50 dB (presentation level) minus 10 dB (threshold), which equals a sensation level of 40 dB SL. This is also the procedure for a frequency-specific stimulus (e.g. pure tones): subtract the audiometric threshold (dB HL) from the supra-threshold presentation level (dB HL) and the difference is the sensation level (dB SL).
What do you measure noise in?
If you would like to measure how loud the sound is, dB, decibels, would be good. To give you a rough idea, a whisper is about 30 dB, a baby crying loudly about 100 dB. Also, if you like to measure the frequency or the wavelength, you can use Hertz.
What is the Sound in measure is what unit?

Db is the unit of sound level please tell you full form of the same?
Db stands for "decibels".
What is the softest sound in the world?
20,000 Hz (20kHz) is the (ideal) highest FREQUENCY that a healthy human ear can hear. With regard to loud sounds, a sound LEVEL of 120 decibel (dB) causes pain, and a level of 140 dB causes deafness.
What is the dB rating for pain threshold?
If you mean the sound pressure level that causes pain, it is about 120 dB SPL.
