A-weighted decibels to decibels

1 A-weighted decibel in decibels
1 dB(A) = 1 dB
dB = dB(A) × 1

To convert A-weighted decibels to decibels, multiply by 1. The table below gives the values people look up most often, and the converter works for any number.

A-weighted decibels to decibels table

Common A-weighted decibel values converted to decibels.
A-weighted decibels Decibels
1 dB(A) 1
2 dB(A) 2
3 dB(A) 3
4 dB(A) 4
5 dB(A) 5
10 dB(A) 10
15 dB(A) 15
20 dB(A) 20
25 dB(A) 25
30 dB(A) 30
40 dB(A) 40
50 dB(A) 50
75 dB(A) 75
100 dB(A) 100
250 dB(A) 250
500 dB(A) 500
1,000 dB(A) 1,000

How the conversion works

The relationship is dB = dB(A) × 1. Both units measure sound, so the conversion is a fixed factor that never changes.

A-weighted decibel: Weighted to match human hearing sensitivity; the standard measure for noise exposure.

Common questions

How many decibels are in one A-weighted decibel?
One A-weighted decibel equals 1 decibels. dB = dB(A) × 1.
How do you convert A-weighted decibels to decibels?
Use dB = dB(A) × 1. So 10 dB(A) is 10 dB.
How many A-weighted decibels are in one decibel?
One decibel equals 1 A-weighted decibels, which is the reverse of the conversion above.
Is there more than one kind of A-weighted decibel?
Weighted to match human hearing sensitivity; the standard measure for noise exposure.
