Sound Reduction Numbers - What do they mean?
At VocalBooth™ our priority is that you are as confident as we are about your VocalBooth purchase. We understand that comparing sound reduction numbers with competitive products can be confusing and misleading. It's a frustration to us as well that there is not an industry standard for testing. We'll illustrate how we do our testing. Bottom line—we do it differently. We believe the way we test our booths from a technical and practical approach is the most accurate available. We could get higher sound reduction numbers using other methods but we choose not to. At VocalBooth our goal is to provide you with an honest reading that makes sense verses one that just makes us look good on paper. We hope you feel the same.
The VocalBooth.com testing method for sound reduction numbers.
Step 1: By using two speakers 8' apart we are creating a volume sound instead of directional sound. This best mimics typical room environments where sound is distributed in all directions.
Step 2: Placing a booth around the microphone will show the volume reduction of the distributed sound without changing the ratio of the initial sound to microphone measurement.
