Sound Diffusion Explained in a Short Video Demonstration

Acoustics First has released a new educational video to help demystify sound diffusion. Using an array of ping pong balls to represent sound visually, this video simply demonstrates what occurs when sound strikes an diffusive surface.

Acoustics 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.

ELK Products -C1M1 Dual-Path Alarm Communicators with Remote Services

C1M1 offers a truly significant reduction in transmission time in comparison to other communicators that rely on dial capture or data bus decoding. This can result in quicker response time to emergency situations which could save lives and assets. By providing both IP and cellular pathways, C1M1 provides the reliability installers are looking for in an alarm communicator. C1M1 eliminates port forwarding and extra fees for remote access. Installers can remotely upload/download programming changes to M1 controls over IP or cellular using ElkRP2. Consumers can control the M1 remotely via the free ElkLink mobile app and web portal, as well as eKeypad and M1 Touch Pro apps. Other IP-based software and interface partners can connect to the M1 control over the local network through C1M1. C1M1 also provides email/text notifications for arm, disarm, and alarm events. ELK-C1M14GSM supports GSM (AT&T/T-Mobile) networks and ELK-C1M1CDMA supports CDMA (Verizon) networks.
