The most common sensor used for acoustic measurement is the microphone.

The first acoustic measurement of sea depth was made in 1914.

Sea depth by acoustic measurements of was first made in 1914.

Early systems used bolted-down directional microphones and careful acoustic measurements of the room to reduce echoes.

Actual acoustic measurements taken in real locations are translated into digital information incorporated into a computer chip.

For measuring the average temperature of ocean basins, therefore, the acoustic measurement is quite cost effective.

The craft offer an advantage over surface vessels because they can dive down to take acoustic measurements near the particular species that is targeted.

The accepted gold-standard for quantitative acoustic measurement is the hydrophone.

Three additional possibilities to evaluate the bond connection are optical, electron and acoustic measurements.

However, acoustic measurement is almost always required in this case, since the phase adjustment cannot be done by hearing alone.
