Why is RT60 Duration Important in Conference Hall Acoustics?
Another topic as important as aesthetic design, seat comfort and visual equipment in conference hall projects is the acoustic performance of the hall. One of the most basic measurable components of acoustics is the reverberation time called RT60 (Reverberation Time – 60 dB). This concept refers to the time it takes for the sound energy in the environment to decrease by 60 decibels after a sound source stops.
RT60 time is a critical criterion that shows how long it takes for the sound in the hall to be attenuated. The clarity, intelligibility and homogeneous distribution of the speech sound are directly related to this period. RT60 value plays a decisive role in terms of overall usage efficiency, especially in places where verbal communication is essential, such as conference halls. Duration
The ideal RT60 duration recommended in conference rooms is generally between 0.6 and 0.9 seconds. This value range is considered optimum for the speaking voice to be heard clearly and intelligibly at every point in the hall. When the RT60 time exceeds this value, conversations become blurred, echoes cause words to overlap, and communication effectiveness within the hall is seriously reduced. Problems
The following problems occur when the RT60 time is longer than it should be observable:
Conversations become unintelligible comes.
Participants listen quickly. gets tired.
Efficiency of communication-oriented activities such as presentations and panels drops.
Technical quality and corporate perception of the hall
Therefore, it is not enough to just build a visually stylish hall; If the sound is not controlled, the functionality of the hall will be greatly damaged. Factors
Main factors that directly affect RT60 time in a conference room are:
1. Volume of the hall (height, width and depth relationship)
2. Sound absorption coefficient of the materials used on wall, ceiling and floor surfaces Type and number of seats
4. Whether the floor is carpeted or hard-covered Occupancy rate of the hall (echo time is different when empty and occupied) Approach
As Nish Global, we develop special acoustic solutions in each project, taking into account the volume, purpose of use and target audience of the hall. RT60 time is not just a theoretical calculation, it is the basis of the entire system. Among the services we offer in this regard:
Preliminary acoustic analysis and RT60 estimated
Proper ceiling and wall panel systems Determination
Absorption according to the relationship between seat and ground calculation
RT60 tests with field measurement devices are available upon request.
Conclusion
RT60 Duration is not just an acoustic detail of conference rooms, but a determinant of the total communication quality. An effective sound distribution, clear echo control and homogeneous acoustic environment reveal the true potential of the hall. Therefore, acoustic planning should always be at the center of the project planning process. has been prepared.
