The phrase "average sound level" is correct and usable in written English.
It can be used in contexts related to acoustics, audio engineering, or any discussion involving sound measurement.
Example: "The average sound level in the concert hall was measured at 85 decibels, ensuring a comfortable listening experience for the audience."
Alternatives: "mean sound level" or "typical sound level".
An attempt is made to reduce the average sound level over a head height plane covering all 48 passenger seats.
In our department, measures should be taken to reduce the average sound level and the incidence and magnitude of sound level peaks".
The WHO recommends an average sound level of below 35 dBA in hospital wards during the day and says it should not exceed 40 dBA at night.
There are limits on airplane noise; the federal government uses a measure called a day-night average sound level, which averages airplane noise exposure over a year.
Under those standards, at 99 decibels (the average sound level recorded one recent Saturday night at Beaumarchais, a restaurant in Manhattan) the maximum recommended exposure is 19 minutes.
Accordingly, while larval animals might not be able to hear the average sound level at any appreciable distance from the reef, they might detect some of these transient signals.
In general, average sound levels were low and perhaps too faint to be used as an orientation cue except very close to the reef.
The federal Occupational Safety & Health Administration (OSHA) has a permissible exposure limit for noise that is an 8-hour time-weighted average (sound levels averaged over an 8 hour day) of 90 decibels (dB) and an action level of 85 dB.
In a recent paper, light-rail line noise exposures were predicted both in terms of maximum pass-by sound levels for comparison to APTA criteria and day night average sound levels for comparison to FTA criteria.
Average sound levels always exceeded 45 dBA and for 50% of the time exceeded between 52 and 59 dBA in individual ICUs.
The noise signals were recorded so that we can assess noise exposure following indices based on A weighting (Equivalent sound level «LAeq», Sound Exposure Level «SEL», 10 percentile-exceeded sound level «L10» (the A-weighted sound level occurred at 10% or more of the time of the measurement; 95% in case of L95), «L95», Day-night averaged sound level «LDN», Level Day Evening Night «Lden»,…).
