gypsum or the like to reduce the transmission of energy between the wall stud and the wall structure as can be seen the energy transmission control mount 10 comprises a generally rectangular carrier 12 formed of metal such as for example steel the top and bottom ends 14 and 16 of the carrier 12 are folded back over the front surface 18 of the carrier 12 to define channels 20 vibration dampening material 22 substantially lines each of the channels 20 a central aperture 26 is also provided through the carrier 12 vibration dampening material 30 substantially lines the aperture 26 and extends over a portion of both the front surface 18 and the back surface 32 of the carrier 12 the vibration dampening material 22 and 30 may be for example polyurethane bonded recycled rubber polyether urethane foam or other suitable energy absorbing material on the back surface 32 the vibration dampening material 30 is configured to define a plurality of vertically and generally equally spaced horizontal ribs 34 on the front surface 18 the vibration dampening material 30 is configured to define a disc 36 on which a washer 38 is disposed the vibration dampening material 30 substantially lines the aperture of the washer 38 and forms an annular flange 40 over the washer 38 to retain the washer on the disc 36 the vibration dampening material 22 substantially lining the channels 20 is isolated from the vibration dampening material 30 substantially lining the aperture 26 and extending over the front surface 18 of the carrier 12 the vibration dampening material 22 and 30 is permanently bonded to the carrier 12 turning now to fig3 the energy transmission control mount 10 is shown in use interposed between a wall stud 50 and drywall 52 energy transmission.
