Abstract : A series of simultaneous hourly measurements of ambient noise at a number of depths between 100 and 12,000 feet shows a gradual reduction of noise level with depth. This decrease is most rapid at shallow depths and is less rapid at great depths. Individual noise profiles show considerable variability, some depths being at times more noisy, and at other times more quiet, than others. (Author)
