Abstract

Study of sound made by marine species aid in ambient noise studies and characterization. This letter presents the work carried out on measurement of sound made by lobsters in a controlled environment and the data processing and the spectral analysis to identify the frequency contents. Lobsters collected in the shallow waters as well as deep waters in the ocean have been used for the sound measurement. The Panulims Homarus and Palinustur Waguersis species were kept in a tank in a laboratory and measurements were made. Their fundamental frequencies, harmonics, and peaks are analyzed in the band 3 to 100 kHz under different conditions such as molting and nonmolting states. Analysis with respect to diurnal variations is also carried out. The results show that lobsters produce sound like musical instruments, which agree with the observations of Patek Nature (London) 411, 153-154 (2001).
