Outline of Sound and Vibration Measuring Instruments

Sound and vibrations are always present in our surroundings. Therefore it is no surprise that
measuring instruments such as sound level meters and vibration level meters are used in a wide
variety of situations on a daily basis.

Some examples of sound related applications:

Reverberation time measurements of concert halls and other venues
Sound insulation measurements of apartment buildings and other dwellings
Quality control, inspection, and R & D of automobiles, machinery, electrical goods and other industrial products
Maintenance of large industrial machinery
Environmental noise monitoring in factories, cars, airplanes etc.
Designing an improved work environment
Voice analysis and vocal training in the medical field
Field studies of birds, fish or other animals

Some examples of vibration related applications:

Inspection and quality management of industrial products
Vibration testing during product R & D
Early fault detection in large industrial machinery
Equipment and facility maintenance and error diagnosis
Monitoring of environmental vibration related to traffic and other causes
Evaluation of the effect of vibrations on human health and well-being

Sound and vibration measurements are vital for many aspects of our daily lives and contribute significantly to the creation of a quieter and safer environment.
