Acoustics in Industry
The field of Acoustics is essential to Industry. Applications are wide ranging and include:
- Protecting workers hearing
It is a common site to see workers wearing hearing protection. Whenever you see this, a noise at work assessment will have been carried out by an acoustic consultant. Ensuring the correct hearing protection is crucial, too little could still mean hearing damage, too much could make it hard to hear warning alarms and sirens.
- Minimising the impact of industrial noise on the surrounding area.
Factories and industry centres are often in close proximity to housing. In order to co-exist it is good practice that industry seeks to minimise its noise output into the local environment. This reduces the risk of noise complaints.
- Active monitoring of equipment to detect faults early.
More and more it is becoming commonplace that machinery is monitored using acoustic and vibration sensors, this allows an engineer to detect developing issues before they become an issue that would cause the machinery to breakdown completely and saves time and money for businesses.
- Sonar surveys of the seabed.
A ship towing a sonar array is able to survey and inspect the seabed from the surface. This has been used to for oil prospecting, search and salvage operations and coral reef monitoring.
