Hi everyone, As an acoustics consulting firm, we get a wide variety of projects. Recently, we've been asked to investigate the mechanical systems of a 40-yr old condo bldg. The retiree owner/ occupants hear "strange bumps in the night". Unfortunately, the pesky sound never shows up when we're on site to pin down its source. Any pointers or suggestions are most welcome! |
