In efforts to help you make those decisions regarding which type of sound should be coming out of your audio indicator. Mallory Sonalert has prepared an article to help you with your decision making.
These days, it seems that we are constantly being alerted with everything from beeps to buzzers with the many different audio indicators available. Personal Computers, virtually all types of home appliances, cars, farm implements, golf carts, medical equipment, instrumentation, and smoke and carbon monoxide detectors. These all contain audible alarm devices which notify us of events warranted by the manufacturer. But what types of alarms are available? And how does a manufacturer decide what specific alarm is best suited for their particular application? First of all, there are many different kinds of audible alarms out there which can create a myriad of continuous and intermittent sounds. Two of the most popular technologies used in audio indicators are piezo-ceramic transducers and electro-magnetic type technology. Both of these audio indicator technologies have two primary components: 1) A base material mounted within a sound chamber. 2) A drive circuit which supplies an output that is applied to the base material causing deflections. The deflections of the base materials, in turn, cause variations in the air pressure within the sound chamber and create the audible sound. Different base materials mounted in various sized sound chambers (with specifically designed drive circuits) create the variances in the audible alarms. (more…)
