Easy to understand video demonstrations

Acoustic Diffuser DemonstrationAcoustics First has just released another in a series of videos to help explain acoustical principles using simple, easy to understand video demonstrations. This latest demonstration tackles the mystery of acoustic sound diffusion. Using an array of ping pong balls to represent sound visually, this video simply demonstrates what occurs when sound strikes the surface of an acoustic diffuser. First, you will see what happens when sound hits a flat reflective surface with no acoustical treatment. The balls all bounce Acoustic Sound Diffuser (Art Diffuser Model C)at the same time and in the same direction. This represents what happens to the sound when it hits a flat reflective surface like a wall. Then you see what happens when sound hits an acoustic sound diffuser. You will immediately notice the energy of the wave of balls is scattered in all different directions as well as deflected at different time intervals. Diffusers, disperse or scatter the sound like crowd control, preserving the sound to maintain sound clarity without destructive interference. This is the basic principle behind acoustic sound diffusion. Click here to view the demonstration: DIFFUSING / SCATTERING SOUND: Sound Diffusion Explained

The kit allows use of the video entry phone system via a door entry monitor as well as tablets and smartphones on the Wi-Fi network, or remotely on 3G (or higher) networks. The gateway in the pack allows connection of other devices (Comelit VIP door entry monitors or PCs) besides the door entry monitor supplied. In all cases, the gateway should be connected to an ASDL router or another device guaranteeing local Wi-Fi and mobile 3G connectivity. Depending on bandwidth limitations, the gateway can serve up to 15 appliances (including door entry monitors, smartphones, tablets and PCs) with 4 simultaneous door entry monitor streams. It also allows "intercom" communication between all of the 16 devices served. For mobile devices, whenever both modes are available and enabled, the app automatically switches. .
