Marico: Reducing Echo in a Meeting Room
A meeting room at Marico suffered from strong reverberation and echo that hurt speech clarity and online meetings. Silence inspected the room, chose the treatment using acoustic principles, and installed absorption panels at calculated points, making the room clearer for in-person and online meetings.

The challenge: when echo makes communication hard
The meeting room at Marico suffered from strong reverberation and high echo, which directly affected speech clarity inside the room.
During online conferences, repeated sound reflections made speech harder to pick up and understand, even with microphones. As a result, the room was unsuitable for meetings that need clear sound and effective communication between participants.
The problem was not the equipment alone, but the acoustic characteristics of the room itself.
The solution: acoustic treatment built on science
The Silence team started by inspecting the room and assessing the acoustic problem, to identify the causes of the echo and the reflections affecting speech clarity.
We chose the treatment based on the principles of acoustics, taking into account the room volume, the reflective surfaces and how the room is actually used.
The science behind it: reverberation time (RT60)
Reverberation time (RT60) is one of the key measures used to assess a room’s acoustics: the time it takes for sound to drop by 60 decibels after the source stops.
Sabine’s formula is used to estimate it: RT60 = 0.161 × V / A (V = room volume, A = total absorption).
Based on the inspection, we defined the treatment and the mounting points for the absorption panels, to reduce reflections and improve speech clarity in the meeting room.
Installation: fitting the acoustic panels
The Silence team installed the acoustic panels at the defined positions, according to the room’s layout and acoustic needs, to limit echo and improve the meeting environment.
The work focused on treating the reflections in the room, not simply adding acoustic elements to the interior design.
The result: a clearer meeting room, better for communication
The treatment solved the echo problem that had been limiting the room, and improved speech clarity and the acoustic conditions needed for meetings.
The room is now better suited to both in-person and online meetings, with an acoustic environment that makes communication clearer and more comfortable.
Does your meeting room have the same problem? If echo is hurting speech clarity or online-meeting quality, the right acoustic treatment can improve the room for the way you use it.
