The phrase "a sound level of" is correct and usable in written English.
It can be used when discussing measurements or standards related to sound, such as in acoustics or audio engineering.
Example: "The concert was set to a sound level of 100 decibels to ensure an immersive experience for the audience."
Alternatives: "a noise level of" or "a volume level of".
Thus speech of intensity 10-12 watt per square centimetre has a sound level of b = 10 log10-12/10-160-16) = 40 decibels.
If the government's proposal goes into effect, beginning in 1979 it will be illegal to manufacture a garbage truck that produces a sound level of more than 78 decibels.
One sone is arbitrarily set equal to the loudness of a 1,000-hertz 1,000-hertzound level of 40 decibels above tonestatdard reference level (i.e., the minimum audible thresound).
The auditory stimuli (1 or 2) were presented using an external speaker with a machine voice, the volume was maintained constant during all experiments at a sound level of approximately 50 dB measured at 1 m from the speakers.
Habituation of sleep to the noise of a ship with a sound level of 60dB(A) was observed to some extent in the subjective sleep parameters but not in the sleep parameters measured by actigraphy.
For the next eight consecutive nights, the subjects were exposed to the noise of a ship's engine with a sound level of 60dB(A) (the International Maritime Organization Standard) previously tape-recorded in a room of a diesel engine ship.
The effects of a steady sound level of 65 dB(A) from a diesel ship engine on nocturnal sleep were studied using polygraphic and subjective sleep parameters.
In summary, this study demonstrates that in auditory phantom percepts, similarly to normal audition, there is a sound level dependent activation of the contralateral auditory cortex.
Nevertheless, there is now considerable evidence that a mean sound level of about 47 dB(A) such as that achieved in the present study consistently leads to moderate impairment of endothelial function in healthy controls [ 6] and to a substantial impairment of FMD patients with established or increased risk for coronary artery disease respectively (present study).
Also saw demonstration of a Sound Level Meter, a pocket-size device for measuring the amount of noise in any given place.
Cavitation occurs in two regions, within the flow domain, causing an objectionable sound level of the device and a reduction in filling efficiency.
