Acoustic noise

As with any other hydroacoustic systems, the quality of the EM 712 echo data and
presentations are subject to unwanted acoustic noise. The echoes from any large and
small target must be detected inside the noise.

It is important that we keep the noise level as low as possible. The is necessary to obtain
long range and dependable interpretations of the echoes. Even with the advanced noise
filtering offered by the EM 712, we must address the noise challenge. This is important
during the planning and preparations for the EM 712 installation.

Contributing factors

Several factors are contributing to the performance of the hydroacoustic equipment
used on board a vessel.

Factors contributing to the performance of the hydroacoustic equipment used on board a
vessel are:

• The quality and properties of the transmitted signal

• The quality of the receiving system

• The operational settings made during operation

• The properties of the target(s)

• The signal-to-noise ratio

The majority of these factors can neither be controlled nor improved by means
of installation methods or transducer locations. The quality and properties of the
transmitting and receiving systems are key factors during our product development, while
our end user documentation aims to help the user to make the right filter settings during
operation. As for the target properties, there is nothing any of us can do with those.

The

signal-to-noise ratio

, however, can be improved by making the correct choices

during installation.

Signal-to-noise ratio (often abbreviated SNR or S/N) is a measure used in
science and engineering that compares the level of a desired signal to the level of
background noise. It is defined as the ratio of signal power to the noise power, often
expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more
