Acoustic metrology involves the measurement of quantities such as sound pressure, sound intensity, sound power, loudness, and hearing loss. It includes the measurement of parameters related to ultrasound, underwater acoustics, and airborne sound, as well as acoustic impedance, sound energy, sound transmission loss, and hearing.
Underwater acoustics metrology has become a powerful tool for ocean research and utilization, as well as for detection, navigation, and communication. It has extensive applications in national defense and economic development. Acoustic instrument metrology is of great significance for ensuring measurement accuracy, promoting technological progress, and safeguarding national security.
