Installing Poly Max™ Polyester Acoustical Wall Panels

If you’ve decided to acoustically treat a room, you can use absorptive acoustical wall panels to reduce some of the excess energy of reflected sound resulting in clearer and more-accurate sound. By removing some of the reflected sound energy – but not all of it – our ears and brains are better able to focus […]

Installing a Standard Acoustic Panel

If left acoustically untreated, the acoustical properties of spaces can be significantly diminished. Sound travels so fast that it fills a room almost instantly. It can also propagate from sources in up to 360 degrees, so it’s easy to imagine how a room with flat, highly-reflective surfaces will create a nearly infinite number of sound […]

Installing Echo Eliminator Wall Panels

If left acoustically untreated, large, open spaces like some restaurants, school gyms and cafeterias, shopping malls, or sporting venues, to name a few, can generate tremendous volumes of echo and reverberation, making individual as well as public communications very difficult if not outright irritating and hazardous to our health. Public address or speaker systems often […]

Installing a Soundproof Door

Whether at home or work, you may need or desire to soundproof a room. Doctors, legal professionals, and business executives, for example, all require speech privacy and confidentiality as well as freedom from external noise which may interrupt their work and conversations. Hotel owners often want to soundproof room doors to provide their guests complete […]

Acoustic Panels – What and Where

Acoustical treatments involve only two types of acoustic panels: absorbers and diffusers. Absorbers serve to soak up some of the excess reflected sound in a room. Diffusers, on the other hand, help to spread out the reflections in a room. Combining absorption and diffusion results in clearer, crisper, more satisfying acoustic experiences because it maintains […]

How Sound Works in Rooms

Introduction Most rooms have highly-reflective, flat walls, ceilings, and floors, and they can be a lot like echo chambers if left acoustically untreated. If you’ve ever been in an empty apartment or house, you’ll be familiar with the way sound reverberates in empty spaces. We know that too much reverberation or echo makes for unsatisfactory […]

Your Brain on Sound – Understanding the Fundamentals About Sound & Hearing

Understanding a few fundamentals about what sound is and how we hear it will help you better understand how acoustics work. Our sense of hearing is a finely-tuned evolutionary adaptation to our environment, one of the critical tools in our survival kit. Understanding how sound and hearing are related better enables us to control, shape, […]

What You Need to Know About Acoustics

Do you ever find yourself at your office, at a busy downtown intersection, in an industrial plant, a restaurant or a studio, or simply in your home, and you’re unhappy because unwanted noise is interfering in your life? If so, you’re far from being alone. Noise pollution comes in many different forms and under many […]

The ‘Long View’ of Sound

There’s a moment early in the movie “Men In Black” – after a big green alien has raised “all his hands and flippers” (and was then blasted into goo) – where a tired-out Agent D says to Agent K “They’re beautiful, aren’t they?” K replies “What?” And D says “The stars. We never just – […]
