The Total Isolation System masks sound through the use of a set of custom fitted Challenger S isolation earphones and a Marsona white noise generator. Result? You probably won’t hear much at all. Which may be a good thing or bad, of course. Priced from around $315.00.
WARNING: Using the Total Isolation System at a volume that exceeds safe levels can damage your hearing. The Total Isolation System is capable of masking emergency alarms, crying children and other sounds you may want or need to be able to hear, and with the system in place, ordinary alarm clocks may not be loud enough to wake you.
