Abstract:
1. A security masking box for securing and isolating devices capable of detecting sounds in the surrounding environment, comprising: (a) a box, comprising: (b) a sound absorbing material, the acoustic isolation volume between the walls containing said sound absorbing material; (c) a box closure configured and dimensioned to close the box, the box closure comprising: (d) a closure sound absorbing material, the closure acoustic isolation volume between the closure walls containing said closure sound absorbing material, (e) a window for viewing the interior of the box; (f) a support in the interior of the box, the support being arranged to define a portion of the interior of the box; (g) acoustical noise masking device supported on said support within the defined portion of the interior of the box; and (h) an RF sensor provided inside the box and connected to an indicator to show if a device within the box is transmitting an RF signal; whereby when (i) a device which can detect sounds from the surrounding environment is placed within the box, (ii) the box closure is closed and(iii) the acoustical noise masking circuitry is activated, the ability of the device to receive useful sounds from the surrounding environment is substantially compromised.
