Large event halls often face signi
ficant acoustic challenges due to their sheer size and the abundance of hard, reflective surfaces like walls, ceilings, and floors. These reflective surfaces lead to prolonged reverberation times, making it difficult for people to converse or enjoy performances. As experienced professionals in acoustic installations, we frequently encounter these issues in venues such as sports halls, leisure centres, and event spaces, and one of the most effective solutions we offer is the use of acoustic absorption panels for large rooms.
Understanding Reverberation Time and Acoustic Challenges
Reverberation time (RT60) is a key metric in understanding how sound behaves in a large space. RT60 measures the time it takes for sound to decay by 60 dB after the sound source has stopped. The longer the RT60, the more echoey and disruptive the space becomes, making it hard to communicate clearly or enjoy a musical performance.
In a large event hall, reverberation times are typically high because sound bounces off the walls, ceilings, and floors without being absorbed. This excessive reverberation can muddle speech and reduce the overall quality of sound for attendees.
At Torann Acoustics, we offer a free reverberation time calculation to assess how serious the issue is and determine the best acoustic treatment. This calculation allows us to scientifically approach the problem, tailoring our solutions based on precise measurements rather than guesswork.
The Science Behind Acoustic Absorption Panels
The science of acoustic absorption panels is crucial in solving the problem of long reverberation times. Acoustic panels work by absorbing sound waves rather than reflecting them, effectively reducing the overall noise level and controlling reverberation. These panels are typically made from materials designed to absorb a broad range of frequencies, turning sound energy into a small amount of heat through friction.
One of the most important factors to consider when selecting acoustic panels is their absorption class. The best panels, such as the Class A acoustic panels we often recommend, offer the highest level of absorption, making them particularly effective in spaces with high ceilings and large surface areas. In fact, Class A panels can absorb up to 90% of sound that hits them, drastically improving the acoustic environment.
Addressing Space Limitations: Suspended Acoustic Panels
One of the challenges we often encounter in large rooms like event halls is limited wall space. In these cases, suspended acoustic panels become an ideal solution. These panels hang from the ceiling, allowing us to maximize their effectiveness without taking up valuable wall space that might be needed for other purposes.
Suspended panels are particularly effective because they absorb sound from multiple angles, reducing reverberation across the entire room. In spaces where sound reflection from the ceiling is a major contributor to poor acoustics, these suspended solutions can make a significant difference.
Why 60 dB for RT60?
You might wonder why RT60 measures the time it takes for sound to decay by exactly 60 dB. To put it into context, the loudest sound level in orchestral music is typically around 100 dB, while the background noise level in a quiet room is around 40 dB. A 60 dB decay represents a significant reduction in sound pressure, making it a useful benchmark for ensuring that the sound levels drop to an acceptable level after a sound event—whether it’s a conversation, music, or a performance.
