Measurement of Lung Vibration from Low Frequency Underwater Sound in an Animal Model and Divers Using NIVAMS

摘要

This report contains a description of an investigation of the physiological effects of underwater low frequency sound. The work described includes the design, fabrication, and testing of a travelling wave tube for the controlled insonification of small animals under representative conditions. It also contains a description of an experiment conducted on divers in a hyperbaric chamber to determine the frequency response of the human lung and the effects of depth on this frequency response.
