How the U.S. Navy found the key to reducing aboard noise levels

Excessive noise on U.S. Navy aircraft carriers poses a health risk, with levels over 150 decibels during takeoffs, leading to Noise-Induced Hearing Loss among veterans.

Noise Control Engineering LLC addressed this with:

Advanced simulation using Designer-NOISE software to predict noise
Validation with Siemens' Simcenter SCADAS Mobile hardware and Simcenter Testlab software
Noise source identification using Simcenter Solid Sphere Array

They found vibrating structural bulkheads were the main noise source and applied a spray-on damping solution, reducing noise by 5-7 decibels in treated areas.
