About

BuzziSpace RT60

This tool measures room reverberation times and simulates the effect of acoustic products. It helps determine the number of acoustic elements needed to improve room acoustics. The app organizes acoustic solutions by category for easier product selection.

Highlights
  • Measures reverberation times
  • Simulates acoustic product impact
  • Calculates required acoustic elements
  • Organized product catalog by category
  • How-to video guide
Features
Read full description

The BuzziSpace RT60 app is a functional tool that measures reverberation times in small- to medium-sized rooms. In addition to calculating current reverberation levels, the RT60 app allows users to simulate the impact of various BuzziSpace acoustic products on the acoustics of a room and thereby determine the number of acoustic elements required to reduce reverberation times to acceptable levels. The product catalog changed is presented in a more organized arrangement of acoustic solutions by category. These categories are listed as: Wall Mounted, Ceiling Suspended, Acoustic Lighting, Acoustic Furniture, Free-Standing, and Partitions & Screening. By grouping our various acoustic solutions according to these categories, we aim to simplify the process of identifying and adding products to acoustic simulations within the app. A How-To video to walk you through the app has also been added. This video can be accessed via the menu in the app. For additional help, reach out to: www.buzzi.space/contact.
