German term or phrase: noise measurement term
context: Geräuschmessung an Werkzeugmaschinen
"Der sich aus dem Schalleitungspegel ergebende mittlere 1 m-Meßflächen-Schalldruckpegel und der arbeitsplatz-bezogene Emissionspegel dürfen die nachfolgend genannten Werte nicht überschreiten.
Aufstellung d. Maschine in Betriebsräumen 75 dB(A)
Aufstellung d. Maschine in Büroräume 60 dB(A)
..
What I would like to know is what is meant by 1 m-Meßflächen-Schalldruckpegel. Meßfläche is the measuring area or surface, and Schalldruckpegel is noise level or sound level, but how does the 1 m fit in? Can anyone help?

English translation:at one meter distance
Explanation:
I would assume that since sound volume decreases with increasing distance from the source, to keep the measurements comparable and reproducable, one standardizes the distance at which one measures the volume.
In your case that would be the one meter.
I.e. if my assumption above is correct that would be the noise level measured by a measuring area one meter from the source.

1 metre measuring surface for the noise pressure level


Explanation:
They've just hund the surface arera, on which the mùeazsurement is performed to the type of measurement being performed.

You mave have to adjust my choice of words to fity your context better.

See explanation ...


Explanation:
1 m-Meßflächen-Schalldruckpegel = 1 m-surface measuring area of sound pressure level

"1-m-Meßfläche" means that the sound pressure emitted from 1 square meter of surface area is being measured to determine the sound pressure level.

Schalldruck = Sound pressure (most commonly used), sonic or acoustic pressure

Schallleitungspegel = Sound conductivity level

Hope this helps.
