[QUOTE="Sarel.wagner, post: 1107329, member: 25509"] Around the year 1500: Leonardo Da Vinci wrote “an average human looks without seeing, listens without hearing, touches without feeling, eats without tasting, moves without physical awareness, inhales without awareness of odor or fragrance, and talks without thinking.” I can only hope that last bit is not me. Wait but why? The start of Psychoacoustics: Aristotle (around 350 BC) was the first to suggest that sound is carried by air movement. But Leonardo De Vinci (around 1500) was likely the first to realize that such movement was probably in the form of waves. Galileo Galilei, 100 years later, scraped a chisel across a brass plate, producing a screechy pitch. Galileo calculated that the spacing of the grooves caused by the chisel was related to the perceived pitch of the screech. However, it wasn’t until the 17th century that the relationship between vibratory frequency and pitch was confirmed. Robert Hooke (1635-1703) made a wheel with small teeth sticking out from the edge at equal intervals. As the wheel rotated on an axle and the teeth pressed on a card, a sound was produced when the card vibrated. The pitch of the sound rose as the wheel’s rotational speed increased. And here we are today, trying to figure out vibrations to make sound. As someone once said: They keep on stealing my inventions more than a 100 years ago! :ROFLMAO: Groetnis [/QUOTE]
