| Abstract: | Results of weekly field observations over 1 yr on the acoustic ambient noise levels at 3 stations in the Cochin backwaters are presented. The recorded noise are subjected to a 1/3 octave analysis using audio frequency spectrometer and oscilloscope. Monthly variations of ambient noise show 2 maxima and 2 minima which are closely related to the population variations due to the occurrence of the 2 monsoons. In the higher frequency range monthly variations of the ambient noise have been found related to the shrimp population of the backwaters. Throughout the year the pressure spectrum level shows a marked decrease with increase in frequency. |
