The effect of fluid loading on the generation of extraterrestrial sound
The effect of fluid loading on the generation of extraterrestrial sound
In recent years increased attention has been paid to the potential uses of acoustics for extraterrestrial exploration. Acoustical instrumentation can be deployed in gas, liquid, or solid media for measurement. This report deals specifically with acoustic sensors in gaseous media. Given the variety of atmospheric conditions that could be encountered in other worlds, and the cost and effort associated with sending sensors to them, it is vital that predictive modelling be done to inform the design of the instrumentation and associated acquisition systems, and for mission planning. To this end, it is important to revisit assumptions which have become embedded in our predictions for acoustics in Earth’s atmosphere. This report deals specifically with the issue of fluid loading, and assesses the extent to which the radiation mass associated with immersion of an acoustic source in a gas (an effect which is usually negligible on Earth) affects its resonance frequency.

Abstract
In recent years increased attention has been paid to the potential uses of acoustics for extraterrestrial exploration. Acoustical instrumentation can be deployed in gas, liquid, or solid media for measurement. This report deals specifically with acoustic sensors in gaseous media. Given the variety of atmospheric conditions that could be encountered in other worlds, and the cost and effort associated with sending sensors to them, it is vital that predictive modelling be done to inform the design of the instrumentation and associated acquisition systems, and for mission planning. To this end, it is important to revisit assumptions which have become embedded in our predictions for acoustics in Earth’s atmosphere. This report deals specifically with the issue of fluid loading, and assesses the extent to which the radiation mass associated with immersion of an acoustic source in a gas (an effect which is usually negligible on Earth) affects its resonance frequency.
