View my main page with all my artworks What is a sound diffuser anyway? Acoustic diffusers are specially crafted sound treatment structures that diffuse an incoming sound evenly. Typically, a sound that strikes a surface is absorbed, reflected, or transmitted. Diffusers are typically used in concert halls, performance venues, and recording studios. The choice of building material to make a diffuser is endless. Source: wikipedia Some history about sound and architecture… After the Greco-Roman antiquity, Leonardo da Vinci (1452-1519) realized that air was needed, among other things, as a means of spreading sound and that the sound spread at a finite speed. Physical study and interpretation of acoustics made significant progress with Galileo (1564-1642) and his contemporary, Marin Mersenne (1588-1648), who determined experimentally the mathematical relationships between frequency, length, mass of a vibrant string, completing the work of the Pythagoreans 2000 years ago. Between 1630 and 1680, many researchers, including Mersen, conducted experimental measurements of the speed of sound in the air. From the 19th century until the 19th century. many scholars have devoted their studies to hearing problems. However, all were limited to studying the physical phenomenon and much less to normal acoustics and psychoacoustics. Source: wikipedia
