Sound Leak Project at a Glance
- Environmental Noise Control, Inc. deployed acoustical visualization (beamforming) techniques to illustrate sound paths.
- ENC’s acoustical engineering study identified unwanted noise impacting filming studios.
- This project utilized ENC’s acoustical visualization (beamforming) technology.
Environmental Noise Control, Inc. was contracted to perform a sound transmission evaluation of an elephant door used for film work at a sound stage at Raleigh Studios in Manhattan Beach, CA.
The studio installed the elephant door between two sound stages to block noise from one stage from transmitting to the other; however, there was still audible noise propagation.
ENC measured sound levels within one stage while generating noise via two prominent speakers. Acoustical visualization (beamforming) illustrated the studio door sound leak paths.
Raleigh Studios benefited from this study by being notified that modifying their door will significantly reduce the noise transmitting between the studio spaces.
