Sound Level in Bels Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sound Level in bels = log10(Sound Pressure Level/Standard Sound Pressure)
L_b = log10(dB/Q_o)
This formula uses 1 Functions, 3 Variables

Functions Used

log10 - The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function., log10(Number)

Variables Used

Sound Level in bels - (Measured in Decibel) - Sound Level in bels is the intensity of sound. It is measured in bels.
Sound Pressure Level - (Measured in Decibel) - Sound Pressure Level is the pressure level of a sound, measured in decibels.
Standard Sound Pressure - (Measured in Decibel) - Standard Sound Pressure is the standard pressure level of sound measured in decibels.

STEP 1: Convert Input(s) to Base Unit

Sound Pressure Level: 850 Decibel --> 850 Decibel No Conversion Required
Standard Sound Pressure: 85 Decibel --> 85 Decibel No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_b = log10(dB/Q_o) --> log10(850/85)

Evaluating ... ...

L_b = 1

STEP 3: Convert Result to Output's Unit

1 Decibel -->0.1 Bel (Check conversion here)

FINAL ANSWER

0.1 Bel <-- Sound Level in bels

(Calculation completed in 00.004 seconds)

Sound Level in Decibels

Go Sound intensity level = 10*log10(Sound Pressure Level/Standard Sound Pressure)

Sound Level in Bels

Go Sound Level in bels = log10(Sound Pressure Level/Standard Sound Pressure)

Standard Sound Pressure given Sound Level in Bels

Go Standard Sound Pressure = Sound Pressure Level/10^(Sound Level in bels)

Sound Pressure given Sound Level in Bels

Go Sound Pressure Level = Standard Sound Pressure*10^(Sound Level in bels)

Standard Sound Pressure given Sound Level in Decibels

Go Standard Sound Pressure = 10*Sound Pressure Level/(10^(Sound Level))

Sound Pressure given Sound Level in Decibels

Go Sound Pressure Level = (Standard Sound Pressure/10)*10^(Sound Level)

Sound Level in Bels Formula

Sound Level in bels = log10(Sound Pressure Level/Standard Sound Pressure)
L_b = log10(dB/Q_o)

What is bel?

The term bel is derived from the name of Alexander Graham Bell, inventor of the telephone. It is equal to 10 decibels.
