A noise source produces sound mainly at 2500 Hz and an SPL of 95 dB at the location of a worker. In order to decrease this worker’s noise exposure, the employer decides to build a brick wall (? = 400 kg/m2) between source and worker. What would the sound level at the worker’s location be after the wall is built. Assume that the wall is perfect and that the sound must go through it (not around it).

The ideal (daytime) noise-level for hospitals is 45 decibels with a standard deviation of 10 db; which is to say, this may not be true. A simple random sample of 81 hospitals at a moment during the day gives a mean noise level of 47 db. Assume that the standard deviation of noise level is really 10 db. All answers to two places after the decimal. (a) A 99% confidence interval for the actual mean noise level in hospitals is...

A communication network has a bandwidth of 10 kHz. Calculate the signal-to-noise ratio in dB if the capacity of the channel for a 100Kbps [2 Marks] ii. A communications channel with a bandwidth of 4kHz has a signal power to noise ratio of 7. Determine the Channel Capacity. [2 Marks] ii. The bandwidth in b above is reduced by 25%. How much should the signal power be increased to maintain the same channel capacity?
