Measuring  sound level for one hour at a known distance from the road.

In sound-speak, 45dB is the level below which acoustic privacy is achieved. Above 45dB, we begin to notice noise (sound) as a distraction.  Below 45dB is tranquility, peace and happiness! As population density increases, acoustic noise and vibration challenges can arise. We believe that, if noise and vibration are managed effectively, everyone can live and work harmoniously. Here at 45dB Acoustics, we see peace and quiet as the next big resource, and we want you to be able to achieve the quietness you need, for whatever it is that you do.

Our engineer/architect team pairs out-of-the-box thinking with tried-and-true acoustics consulting skills. With decades of experience, we utilize cutting edge scientific tools and best-of-industry practices to effectively and creatively find solutions to your acoustics challenges. Head to our Contact page to get in touch!
