dB stands for decibel and is used to measure sound intensity in acoustics

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.

db=20log(V1/V2) or 10log(P1/P2) Example: db=20log (100/50) db=20log(2) db=20*.3010 db=6.02
The "SL" in dB SL stands for "Sensation Level". The "HL" in dB HL stands for "Hearing Level". The difference between them is that dB SL is based on the hearing ability of an individual test subject, and dB HL is based on the hearing ability of an entire population of test subjects. 0 dB SL is the minimum level at which the test subject can hear a stimulus, usually a tone pip. The actual level will vary with frequency. If we refer to a level of, say, 40 dB SL, we mean a sound that is 40 decibels above a test subject's threshold of hearing. The dB HL scale is the mean dB SL of a large population (theoretically the world-population) of *normal hearing* people. They measured frequency-specific thresholds for alot of people, and averaged them to give the dB HL scale. Finally, dB nHL stands for "normalised hearing level". This is the same concept as dB HL, except the number of test subjects contributing to the average is smaller. It is standard practice for a Hearing Clinic to establish their own dB nHL scale based on all the normal-hearing test subjects they have had access to. This allows a clinic to ensure that the scale they use is correctly calibrated to their test equipment.
