Measurements to evaluate and improve Building Acoustics are typically made to analyze and design noise control from room to room, or from outside to inside. Noise sources such as music systems, televisions, appliances, traffic, aircraft, and manufacturing are all around us. The field of Building Acoustics evaluates and designs the materials and methods to insulate and isolate us all from these sound sources when we are at work, rest, or enjoying leisure time. The resulting data is useful for evaluating compliance with building codes and for proposing countermeasures for areas of concern. These measurements often involve creating and measuring an artificial sound source, and then measuring the resulting noise in receiver locations.

Acoustic Modem Option for Control Module
-
Gavia AUVs can be fitted with the Teledyne Benthos ATM-900 Acoustic Modem. The ATM-900 Series Acoustic Telemetry Modem is the most advanced, multipath and noise tolerant, modem available. They are designed to meet both the high data rate requirements of commercial users, and the higher reliability, lower data rate requirements of the military. The modems employ two modulation techniques: phase shift keying (PSK), which provides the highest bit rate, and multiple frequency shift keying (MFSK), which provides reliability in a multipath environment, or when the modems are required to operate in a low signal-to-noise (SNR) environment. The ATM-910 Series can transmit data using PSK modulation for reception by a Gavia Modem Deckbox, but receives data using MFSK modulation only. MFSK modulation is a spread spectrum modulation process that transmits multiple tones simultaneously.
