Noise and speech levels in noisy environments: a S/N ratio of 2-5 dBA was found with sound levelmeter readings in noise
Noise and speech levels in noisy environments: a S/N ratio of 2-5 dBA was found with sound levelmeter readings in noise
Measurements with a portable sound level meter reveal that the signal to noise ratio of conversational speech averages 4.8 dB in noisy environments and substantially less in automobiles. The findings have implications for the design of hearing instruments
