Removing echo in large rooms is often the first step to achieve a comfortable space for users. In fact, traditionally it was aesthetics and decoration that were taken into account when designing large rooms but, sometimes, perhaps because of ignorance, acoustic comfort was neglected.
Large rooms such as exhibition halls, dining rooms, waiting rooms, auditoriums, classrooms or offices tend to exhibit an acoustic problem similar to echo called reverberation. Reverberation is the permanence of sound beyond the time required to properly hear and understand a message. Explained in a more technical manner, “reverberation time ” is the time it takes for the sound to decay by 60 dB as received stood the sound emission source stops. Reverberation in rooms is popularly called echo, and removing echo is called acoustic conditioning.
What steps should I follow when removing echo in a room?
- Measuring the dimensions of a room
- Knowing the level of reverberation of room: When removing echo from a room we must know its level of reverberation. We can know this in two ways: taking measurements with an acoustics specialist or making an estimate with the help of an Optimum Reverberation Time (ORT) calculator like the one Spigogroup offers on its website for free.
- Identify the areas where you can install acoustic panels made of sound-absorbent wood: walls, ceilings, columns, etc.
- Choose an acoustic panel model that will allow you to eliminate the echo and get closer to Optimum Reverberation Time in the room. Again, the ORT calculator can help by guiding you on the most suitable Spigotec or Spigoacustic cladding.
- Choose the finish that best fits the style of the room
