The phrase "a weighted level" is correct and usable in written English.
It can be used in contexts where you are discussing a level that has been adjusted or influenced by certain factors or criteria, often in fields like statistics, gaming, or project management.
Example: "In our analysis, we used a weighted level to account for the varying importance of each factor in the overall outcome."
Alternatives: "an adjusted level" or "a prioritized level".
Relationships between the annoyance and noise levels in terms of linear or A-weighted sound pressure level, linear or A-weighted level difference between noise and background, and level above threshold of audibility were evaluated.
It was concluded that, generally, loudness measures were most closely related to average noisiness ratings, but provided that the frequency spectra of vehicle sounds are not greatly different, loudness measures have no advantage over the A-weighted level currently employed.
The aircraft noise level L (Eq. 8) is A-weighted level.
27 28 Stationary measurements during activity in the various rooms showed a moderate reduction of the equivalent A-weighted level.
Railway noise exposure was calculated as the A-weighted level (LAeq, 24 hr) outside the most exposed facade using the joint Nordic prediction method for railway noise (Lathi 1984), based on general information about rail traffic in 1993 2000.
Road traffic noise was calculated as the A-weighted level (LAeq) at the most exposed façade of the dwelling at each address for the day (07:00-19:00 h), evening (19 00-22 00 h) and night (22 00-07:00 h) and expressed as Lden by applying a 5 dB(A) penalty for the evening and a 10 dB(A) penalty for the night [ 24].
The main results are given as A-weighted levels, but octave band levels can also determined.
Early models predicted linear levels whereas the later models predicted A-weighted levels.
The results indicate that A-weighted levels of noise and measures of loudness were generally superior to B- and C-weighted measures.
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»,…).
