Calibration Measurements of RT 60 in a Traffic Control Room using SVANTEK SV 971A

Introduction

Ensuring Acoustic Compliance in a Traffic Control Room

Reverberation time (RT60) plays a critical role in defining the acoustic quality of enclosed spaces. In environments like traffic control rooms—where operator focus is essential for public safety—acoustic performance must meet strict standards. This study presents a verification of acoustic parameters before and after adaptation works, ensuring that design goals were met and working conditions optimized.

Measurement Operator

Budmal-Art Sp. z o.o.

The project was delivered by Budmal-Art Sp. z o.o., a company specializing in acoustic design and measurement since 1992. With extensive experience in executing complex acoustic projects, the team conducted the RT60 measurements as part of a broader adaptation initiative aimed at ensuring regulatory compliance and high acoustic comfort.

Challenge

Accurate RT60 Measurement According to PN EN ISO 3382 Standards

The key objective was to precisely determine the reverberation time in accordance with PN‑EN ISO 3382, validating the acoustic design of a traffic control room. This involved:

Ensuring acoustic compliance prior to project handover
Evaluating conditions before and after adaptation
Supporting optimal performance and speech intelligibility for system operators
