How loud is 60 decibels?

Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.

What is 1 dB?

Decibel (dB), unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds. … One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio.

How is dB loss calculated?

For instance, if signal A has a power of 20 mW and signal B has a power of 5 mW: 20/5 = 4. Take the log of the the ratio of the signals by pressing the log button on the scientific calculator. For instance: log 4 = 0.602. Multiply this answer by 10 to find the decibels.

Why is dB in negative?

The negative sign on a dB (logrithmic) comparison means that the mesurement was less than the reference where a positive sign means it was more than the reference. So the only way to convert a negative dB indication is to change the reference. For example -2 dBm would be +1 dBu.
