Sound level definition

Sound level means the A-weighted Sound Pressure Level;
Sound level means the weighted sound pressure level obtained by the use of a sound level meter and frequency weighting network, such as A, B, or C as specified in the American National Standards Institute specifications for sound level meters. (ANSI SI.4 - 1971, or the latest approved revision thereof.) If the frequency weighting employed is not indicated, the A-weighting shall apply.
Sound level means the noise level measured in decibels on the A-weighted scale of a sound level instrument that conforms to recognized industry standards and is maintained according to the manufacturer’s instructions.

Examples of Sound level in a sentence

Sound level of the lure speaker was calibrated (B&K Type 2231 Sound Level Meter, Type 4139 ¼” microphone) to 104 dB SPL at the centre of the 8 cm circular start region while the two test speakers were calibrated to 94 dB SPL.

Sound level data is reported in a table that is easily exported into spreadsheet applications for pivot table and chart creation.Smart Search and Cloud Storage Search your recordings based on details such as time, temperature, identifications, or even spectral qualities of the recording.


More Definitions of Sound level

Sound level means the weighted sound pressure level measured by the use of a metering characteristic and weighted as specified in American National Standards Institute Specifications, Section 1.4-1971. The sound pressure level of a sound expressed in decibels is twenty (20) times the logarithm to the base ten (10) of the ratio of the pressure of the sound to the reference sound pressure of twenty (20) micropascals. In the absence of any specific modifier, the level is understood to be that of a mean-square pressure.
Sound level means the instantaneous Aweighted sound pressure level, in decibels, as measured with a sound level meter set to the “A” weighting scale, slow response.
Sound level means the weighted sound pressure level measured by the use of a metering characteristic and weighing A, B, or C as specified in American National Standard Specifica- tion for Sound Level Meters S1.4–1971 or subsequent approved revision. The weighting employed must be specified, otherwise A-weighting is understood.
Sound level means 20 times the logarithm to base 10 of the ratio of pressure of a sound to the reference pressure. The reference pressure is 20 micropascals (20 micronewtons per square meter). NOTE: Unless otherwise explicitly stated, it is to be understood that the sound pressure is the effective (rms) sound pressure, per American Na- tional Standards Institute, Inc., 1430 Broadway, New York, New York 10018.
Sound level means the level, in decibels, measured by instrumentation which satisfies the requirements of American National Standard Specifica- tion for Sound Level Meters S1.4–1971 Type 1 (or S1A) or Type 2 if adjusted as shown in Table 1. This publication is available from the American National Standards Institute, Inc., 1430 Broad- way, New York, New York 10018. For the purpose of these procedures the sound level is to be measured using the Aweighting of spectrum and either the FAST or SLOW dynamic averaging characteristics, as designated. It is ab- breviated as LA.
Sound level means the A-weighted sound pressure level measured with fast response using an instrument complying with the specification for sound level meters of the American National Standards Institute, Inc., or its successor bodies, except that only A-weighting and fast dynamic response need be provided.
Sound level means the weighted sound pressure level obtained using a sound level meter and frequency weighting network as provided in the American National Standards Institute (ANSI) specifications for sound level meters. As used in this chapter, "sound level" means the same as "noise level."
