Who
We Are
E4 Acoustics is the Midwest corridor's dedicated acoustical testing partner. We travel to your facility, take calibrated measurements of noise, reverberation, sound transmission and system performance, and deliver a clear report that tells you exactly what's happening with your sound — and what to do about it.
We work with commercial, institutional and public-sector clients only: government & military, retail, restaurants, bars, arenas, casinos, music venues, colleges, universities and manufacturing plants. We also perform outdoor environmental noise testing for commercial and government clients. We do not perform residential neighbor-noise testing. Please call, email, or live chat to get your project started today.
