How to improve acoustics by calculating reverberation time
In professional spaces, poor acoustics not only affect comfort, but also performance, internal communication and brand image. Calculating reverberation time is a key tool for diagnosing and optimising acoustics in offices, meeting rooms, educational centres, healthcare facilities and other corporate environments.
In this article, we explain what reverberation time is, why it is relevant to your business, and how you can use it to create acoustically efficient and healthy spaces.
What is reverberation time and why does it matter?
Reverberation time (RT) is the period it takes for a sound to decrease by 60 decibels after the sound source is interrupted. In other words, it measures how much sound resonates in an enclosed space.
Excessive reverberation time can cause:
- Poor intelligibility in verbal communication
- Auditory fatigue in users
- Increased noise levels
- Loss of concentration and productivity
Conversely, controlled reverberation time improves:
- Clarity in presentations and video calls
- Team well-being
- Perception of professionalism in visits and meetings
- Acoustic regulations applicable in specific sectors (education, healthcare, etc.)

How is reverberation time calculated?
The calculation of the TR takes several factors into account:
At Mirplay Acoustics, we conduct a comprehensive reverberation time study to help you choose the most effective acoustic solutions and the right amount to optimise each space.
What TR values are appropriate in professional settings?
Each type of space has an optimal range of reverberation time. Some examples for guidance:
Space
Open offices
Meeting rooms
School classrooms
Health centres
Restaurants and cafés
Recommended TR
0,5 – 0,8 seconds
0,6 – 0,9 seconds
0,4– 0,6 seconds
0,4 – 0,7 seconds
0,8 – 1,2 seconds
Values above these ranges result in uncomfortable environments, while values that are too low can make the space sound unnatural.
Solutions to optimise acoustics in your company
Once the RT of each space has been identified, the next step is to apply appropriate acoustic solutions. Some of the most effective include:
- Acoustic wall panels or acoustic ceiling panels
- Acoustic room dividers
- Furniture with integrated acoustic properties
- Technical curtains and absorbent carpets
- Strategic distribution of elements in the space
Controlling reverberation time is not just a technical issue: it is an investment in productivity, occupational health, corporate image and regulatory compliance.
Through a professional acoustic study and the application of specific solutions, your company can transform its spaces into more comfortable, efficient environments that are in line with current standards.
