We founded on Prolad that Acoustics is the science of sound and a branch of physics. The scope of acoustics is not limited to phenomena that can be heard by humans and animals, it also includes phenomena with frequencies so low (infrasound) or so high (ultrasound) that cannot be heard by a normal person. Acoustics are fundamentally important to learning environments. Learning is intrinsically linked with communication, and aural (sound) communication is acoustics. Similarly, learning is about concentration, and external noise is a major distracting factor in education. As an Acoustical Consultant, Prolad believes that ceiling and acoustics should be sustainable, surprisingly functional, and remarkably beautiful.
