Background noise: Keep this as minimum as possible in a normal classroom so that the lecturer does not have to speak louder than the noise to be heard. Also, if background noise is too loud it can cause strain to the vocal chords of the teacher, and students may not hear properly.
Reverberation time: The ideal range is from 0.5 to 0.8 seconds, and it should be possible to readopt the room to reduce the time if a child with impaired hearing joins. You should avoid several reflections interfering with speech clarity.
Sound isolation: Often sounds leak into the classroom from adjoining spaces and cause distraction. School doors are generally lighter unlike acoustical doors which are heavier and block sound.
Identifying the Noise Problem
If staff members or students complain about noise, you must attend to the acoustical problem. Engaging an expert consultant is the simplest and most effective approach to find the real cause.
In schools, some of the common sources causing acoustical disturbance are people in hallways and adjoining rooms and noise created by computers, copiers, and other equipment, outdoor noises, HVAC sounds, and also excessive echoing as per a study conducted.
Professional organizations in the acoustical industry, have recommended databases for finding consulting firms. Some of these are certified by competent authorities which rates the acoustical consultants according to their expertise. Your consultants will check the reverberation time of your space, background noise level, sound isolation, and seal penetrations and any other paths that can allow sound transmission between classrooms.
Often schools have noisy gyms, cafeterias or classrooms. Usually such problems originate from poor acoustics or reverberation. There are many hard surfaces in few of these spaces, and much of the noise bounces around from children, which distorts speech.
Finding Acoustic Solutions
Address acoustics is easiest during construction, but in case of present buildings, this option I not valid. Some effective solutions are upgrading the door gaskets or just replacing the doors themselves and this will stop noise from leaking to adjoining rooms.
Noisy equipment can also cause extra background noise. A brand-new chiller or air handling unit or an old equipment that has not been serviced or cleaned regularly can also make extra noise.
A ventilator, and a HVAC unit for every room, and a duct work that is not insulated can cause distracting noise for students and teachers alike, particularly students sitting close to the ventilators.
