Stennes Acoustics is a Knoxville-based acoustical consulting firm that helps clients solve sound problems in existing buildings. We specialize in practical solutions for issues such as excessive reverberation, poor speech intelligibility, mechanical noise, and inadequate sound isolation.

Our work includes offices, churches and worship spaces, restaurants, lecture halls, recording studios, home theaters, multifamily housing, and other spaces where sound matters. Through professionals calibrated measurements, acoustic modeling, and on-site evaluations, we identify the source of acoustic problems and provide clear, cost-effective recommendations tailored to each space.

Whether the goal is improving speech clarity in a sanctuary, making a restaurant quieter, increasing privacy in an office, or reducing sound between apartments, our recommendations are based on objective data and real-world experience.
