Novelty Test Report III - Phone Booth

When was the last time you made a call from a telephone booth? Was it a private phone call? One that you wouldn't want others outside the booth to hear? Well, we hope not! The next test report in our Novelty Testing series is here, and we're pleased to share the results with you.

We tested a Classic Mid-20th Century Coin-Operated Aluminum Telephone Booth to determine the performance of the booth in regards to sound isolation and speech privacy, and the results probably won't surprise you.

About Our Novelty Testing Program

RAL will be performing a series of self-sponsored tests and publishing the results for wide dissemination across the acoustics community. Send us your suggestions for our next test! We are looking to test commodity materials or systems where data is needed but does not exist due to a lack of a traditional sponsor.

The Rules:

Test samples should be made from commodity materials, no specific acoustical product systems
The tests would not have a conventional sponsor interest, so they are not likely to happen in the acoustical testing marketplace
The results have some utility or interest to the broad acoustics community
