Workplace Acoustical Measurement and Standards
We use the Speech Transmission Index (STI) as an objective measurement of speech intelligibility in your
workspace.
ASTM International sets industry standards on acceptable speech intelligibility measurement methods, ratings, and
protocol. Building Systems Solutions complies with all industry standards and uses best practices when testing
your space for speech privacy. Call us at 763-502-1515, or fill out the contact form here to schedule a testing.
