The ocean is naturally noisy, which would seem to present problems for marine mammals using sound, however, they are well-adapted to natural levels of ambient noise
The Ambient Noise
Management System[TM], combined with specialized foam ear inserts, allows testing in any quiet examination room, without the need for a sound booth.
Also, although the Phraselator had the highest number of correct translations of the three units against ambient noise
, correct translations fell off markedly as phrases were tested against increased levels of pink and white noise.

They achieve this by enclosing the machine in a removable acoustic canopy which results in a reduction of noise levels to between 80dB(A) and 83dB(A) depending on ambient noise
levels, and which can be quickly removed for cleaning and maintenance.
The product removes the noise from older local telephone loops and ambient noise
