The Mobile Phone/PDA Security Masking Box is a sound insulated box for use as a temporary storage location for cellular and other mobile devices in locations at which confidential and sensitive conversations and discussions are being conducted. A pink/white noise generating device within the box generates a masking noise such that the cellular or other mobile devices inside the box are unable to pick up or record conversations outside the box.

1. A security masking box for securing and isolating devices capable of detecting sounds in the surrounding environment, comprising: (a) a box, comprising: (i) an outer box wall;(ii) an inner box wall, said outer box wall and said inner box wall defining an acoustic isolation volume between said outer box wall and said inner box wall,(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: (i) an outer box closure wall;(ii) an inner box closure wall, said outer box closure wall and said inner box closure wall defining a closure acoustic isolation volume between said outer box closure wall and said inner box closure wall,(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. 2. A security masking box as in claim 1 wherein the acoustical masking circuitry is powered by one of at least one battery and an outside electrical source. 3. A security masking box as in claim 1 wherein the box cover closure is connected to the box by a hinge. 4. A security masking box as in claim 1 wherein the window has at least two separated layers of transparent material to increase the sound isolating ability of the window. 5. A security masking box as in claim 1 wherein the interior surfaces of the box are covered with a sound absorbing material. 6. A security masking box as in claim 1 wherein the box and box cover closure are secured in a closed position by a lockable latch. 7. A security masking box as in claim 1 wherein the acoustical noise masking circuitry includes a volume control. 8. A security masking box as in claim 1 wherein the acoustical noise masking circuitry includes an on/off switch. 9. A security masking box as in claim 1 wherein the acoustical noise masking circuitry includes a power on indicator. 10. A security masking box as in claim 1 wherein the box is provided with a caller ID module which uses a wireless protocol for exchanging data to connected to an externally mounted box for securing and isolating devices comprising a microphone for detecting sounds in the surrounding environment, comprising: (a) a box, comprising a sound absorbing material;(b) a box closure configured and dimensioned to close the box, the box closure comprising a closure sound absorbing material;(c) 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; and(d) indicator mounted on the exterior of said box to display the originating number of incoming calls to call numbers received by devices within the box, whereby when (i) a device with a microphone for detecting sounds from the surrounding environment is placed within the box, (ii) the box closure is closed and (iii) the acoustical noise generator is activated, the effectiveness of the device to receive useful sounds from the surrounding environment is substantially reduced. 11. A security noise masking box for securing and isolating devices comprising a microphone for detecting sounds in the surrounding environment, comprising: (a) a box, comprising a sound absorbing material;(b) a box closure configured and dimensioned to close the box, the box closure comprising a closure sound absorbing material;(c) 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; and(d) an acoustical noise generator positioned within the interior of the box, said acoustical noise generator matching the frequency content of the human voice in substantial part, whereby when (i) a device with a microphone for detecting sounds from the surrounding environment is placed within the box,(ii) the box closure is closed, and(iii) the acoustical noise generator is activated,the effectiveness of the device to receive useful sounds from the surrounding environment is substantially reduced. 12. A security masking system comprising the security masking box of claim 11, wherein the acoustical noise generator comprises a rechargeable battery and further comprising an inductively coupled power source for recharging said rechargeable battery. 13. A security masking box as in claim 11, wherein the box closure is connected to the box by a hinge. 14. A security masking box as in claim 11, wherein the acoustical noise generator generates pseudo random pink and/or white noise matching in substantial part the human voice range of frequencies. 15.
