Sound intensity describes the flow of acoustic energy produced by a sound source. Unlike simple microphones and sound level meters, sound intensity measurements accurately capture only the sound produced by the source under test, eliminating interference from other sounds. HGC Engineering provides sound intensity measurement to a wide range of industries from high-tech product manufacturers to power generation.
The state of the art is the measurement of sound intensity
Sound intensity measurement makes it possible to achieve on-site, highly accurate, time-efficient measurements in noisy locations and allows for a more effective design of noise control or improved acoustics.
HGC Engineering uses sound intensity measurement methods to:
- Accurately determine sound power ratings for equipment and products, eliminating the need for expensive acoustical laboratories or anechoic chambers
- Reduce prototype and research and development costs for complex industrial equipment and vehicle noise issues
- Isolate and rank individual sources in a complicated soundfield
- Provide research and development assistance for improved noise control and enhanced sound quality
HGC has pioneered the use of these methods in new applications including gas turbine exhaust stacks, development of novel acoustical building materials, and measurement of sound absorption. Our client base includes work for companies ranging from TransCanada Pipelines to Xerox to General Motors.
