Sound (noise) exposure levels tabulated in the ANP database are 10-dB down values [19].
However, except at short slant distances where event levels are high, extraneous ambient noise often makes longer measurement intervals impractical and 10-dB down values are the norm.
Chapter 4 is sound, except for 10 db, which is excellent.
The ambient noise must be at least 10 dB lower than the sound pressure levels to be measured.
Readings on the measuring instruments produced by ambient noise and wind shall be at least 10 dB(A) below the sound level to be measured.
Is ΔL according to Table 3 greater or equal to 10 dB? (2.3.2)
The A-weighted sound pressure level of the background noise shall be at least 10 dB(A) below the measurement of the vehicle or AVAS under test.
The background sound level (including any wind noise) shall be at least 10 dB(A) less than the measured tyre rolling sound emission.
Accordingly, a 10 dB increase means a tenfold increase in sound intensity, which is roughly equivalent to a doubling in perceived noise level.
The background noise (including any wind noise) shall be at least 10 dB below the A-weighted noise pressure level produced by the vehicle under test.
The ambient noise level shall be at least 10 dB lower than the sound pressure level to be measured. The device to be tested and the microphone shall be placed at the same height.

As studies of the effects of noise (used to 'calibrate' the noise contours) also tend to rely on 10-dB down values, the ANP tabulations are considered to be entirely appropriate.
The replacement of cast iron brake blocks with composite brake blocks can bring noise reductions of up to 10 dB.
Measurements shall be made on unladen tractors in a sufficiently silent and open area (ambient noise and wind noise at least 10 dB (A) below the noise being measured).
An increase in night-time aircraft noise levels of as little as 10 dB in the 30-60 dB range increases the risk of hypertension in men and women by about 14 %.
Ideally, the response level in each one- third octave band should be at least 10 dB below the level of the same band at location 0.
When the maximum to minimum range of background noise is greater than 2 dB(A) and the level of the background noise is less than 10 dB(A) below the measurement, no valid measurement is possible.
In both of the measurements, the extraneous noise or signal shall be at least 10 dB below the limits of interference given in paragraph 6.2.2.1 or 6.2.2.2 (as appropriate) of Annex I, except for intentional narrowband ambient transmissions.
Surveys show that the noise emission values of equipment for use outdoors of the same power currently on the market can differ by more than 10 dB.
