We are the only acoustics and audio specialists that you've ever heard of.

21dB is a design and engineering office specialized in acoustics and audio. We study spaces using advanced simulation software to define:

1- The correct geometry and materials required for a quality interior sonic environment.

2- The technical requirements for partitions to achieve the desired soundproofing.

3- The characteristics and details of sound systems to ensure an even sound distribution with superior clarity.

Architectural Acoustics

Good acoustics are essential for comfort, and thoughtful design that complements architecture and materials is key to creating quality sound environments. A space’s soundscape shapes how we feel—a gentle water stream soothes, while a noisy restaurant can frustrate. Whether it’s a restaurant, gym, cinema, concert hall, or museum, we design acoustics to enhance every experience and make spaces sound—and feel—better.

Noise & Vibration Control

Studying how sound travels in and around buildings is key to planning effective preventive or corrective measures. Our team of engineers and acoustic specialists offers tailored acoustic solutions to meet each project’s unique needs.

Measurement & Analysis

Evaluating how sound travels in and around buildings is essential in planning effective preventive or corrective measures. We offer an extensive range of measuring tools to assess noise source locations and sound levels
