A-weighted sound level means the sound pressure level in decibels as measured on a sound level meter using the A-weighting network. The level so read is designated dB(A) or dBA.
A-weighted sound level means the sound level measured in dBA units with a sound level meter set on the A- weighting network, being a filter designed to approximate the relative sensitivity of the normal human ear to different frequencies of sound;
A-weighted sound level means the sound level in decibels as measured on a sound level meter using the A-weighted network. The A-weighted network is the network for measuring sound that most closely resembles what the human ear hears. Sound measured using the A-weighted network is designated dBA.
More Definitions of A-weighted sound level
A-weighted sound level means the sound level in decibels, reported as measured by a sound level measuring instrument having an “A”-weighting network which discriminates against the lower frequencies according to a relationship approximating the auditory sensitivity of the human ear. The level so read is designated dBA.
A-weighted sound level means the total sound level meter with a reference pressure of twenty (20) micropascals using the A-weighted network (scale) at slow response. The unit of measurement shall be defined as DBA.
A-weighted sound level means a quantity, in decibels, read from a standard sound level meter which discriminates against the lower frequencies to which the ear is less sensitive. The A-weighted scale attempts to approximate the auditory sensitivity of the human ear.
A-weighted sound level means the sound pressure level in decibels as measured on a sound level meter using the A-weighted network as specified in the American National Standards Institute Standard S1.4-1983, or its successor provision. The sound pressure level so read is designated dB(A) or dBA.

A-weighted sound level means the sound pressure level in decibels as measured with a sound level meter using the A-weighting network, which compensates for human hearing characteristics. The level so read is designated dB(A) or dBA.
A-weighted sound level means the sound pressure level in decibels measured using the A-weighted network on a sound level meter as specified by the American National Standards Institute specification for sound level meters as now existing or as hereafter amended or modified. The level so read is designated dBA.
