Elastomers for Noise and Vibration Control, Shock Protection and Ergonomics (manufactured by EAR)/
Fan Mounts
E-A-R fan mounts reduce noise and vibration, simplify assembly
 
 
E-A-R’s damped elastomeric fan mounts form resilient connections between a fan and the substrate to which it attaches. Thus they prevent the transfer of structural vibration energy from component to component. This vibration can create unacceptable noise, interfere with equipment accuracy and ultimately shorten product life.
E-A-R’s standard fan mount configurations accommodate a number of the most commonly used fans. They are engineered with a unique design to facilitate assembly - usually replacing metal hardware or rubber mounts with no damping benefits - yet provide secure fastening, and effective vibration and shock control. ISODAMP moldable thermoplastics afford cost-effective custom designs as well.
features

Fan mounts: Performance Date
E-A-R tested the vibration and acoustic spectra of a 12-volt DC axial fan, 60x60x2.5mm, mounted in a satellite television receiver. The hydrowave-bearing(HWB) fan is rated at 32.0db(A). Tests compared two different mounting conditions: a hard mount (without an isolator) and a fan mount molded from ISODAMP C-1002 thermoplastic.- Conducted in a hemi-anechoic chamber with a noise floor level of 26 dBA.
- The graphs here compare the fan’s noise and vibration levels in the two different modes.
| Hard Mount(dB) | ISODAMP C-1002 Thermoplastic Insertion Loss(dB) | |
|---|---|---|
| On Chassis,near fan | 82.4 | -7.4 |
| Chassis cover,top cebter | 77.1 | -8.1 |
| Hard Mount(dB) | ISODAMP C-1002 Thermoplastic Insertion Loss(dB) | |
|---|---|---|
| Forward Acoustic(SPL@0,75m) | 41.4 | -7.4 |
| Overhead Acoustic(SPL@0,75m) | 45.7 | -8.1 |
