Abstract

A measuring device and a measuring method for the acoustic characteristics of a single bubble in water relate to the field of underwater acoustic measurement. The invention aims to solve the existing problem of lack of devices and methods for measuring the acoustic characteristics of bubbles in water. The time synchronization equipment is used to output the time synchronization signal to the air compressor, the preamplifier and the acquisition circuit at the same time, so that the air compressor, the preamplifier and the acquisition circuit work at the same time. The air compressor is used to compress the air in the air gun, and the air gun will compress the air from The air gun nozzle is ejected to make the air generate bubbles in the water. The standard hydrophone is used to collect the bubble sound signal, and the preamplifier and acquisition circuit are used to collect the bubble sound signal of the standard hydrophone. The data is sent to the data storage unit for storage, the high-speed camera is used to collect the bubble image, and the processor obtains the sound level of the bubble sound corresponding to the bubbles of different sizes according to the bubble image collected at the same time and the amplified bubble sound signal. It is used to measure the acoustic properties of bubbles in water.

Description

technical field [0001] The invention relates to an underwater acoustic signal measurement method, mainly relates to an analysis method for the acoustic characteristics of a single bubble in water, and belongs to the field of underwater acoustic measurement. Background technique [0002] The sound characteristics of bubbles in water are the key to the study of bubble sound mechanism in water, and they are widely used in the research of explosion sounds, underwater air gun sounds, electric spark sounds, and high-speed target falling into water. However, most of the research at this stage is focused on the evolution process of bubbles in water, and there is a lack of analysis methods for the sound of bubbles at a certain scale. With the deepening of research, there is an urgent need for a device and method for analyzing the acoustic characteristics of water bubbles. Contents of the invention [0003] The invention aims to solve the existing problem of lack of devices and met...
