To test the noise levels generated by the Akasa Venom Voodoo we use a Type 2 Digital Sound Level Meter. We place the unit about 1 meter away from our chassis on a 4 foot high tripod to simulate a real world situation.
KitGuru noise guide
10dBA – Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refrigerator
50dBA – Normal Conversation
60dBA – Laughter
70dBA – Vacuum Cleaner or Hairdryer
80dBA – City Traffic or a Garbage Disposal
90dBA – Motorcycle or Lawnmower
100dBA – MP3 player at maximum output
110dBA – Orchestra
120dBA – Front row rock concert/Jet Engine
130dBA – Threshold of Pain
140dBA – Military Jet takeoff/Gunshot (close range)
160dBA – Instant Perforation of eardrum
At 1,000 RPM (or just above half their rated maximum) the Viper fans used on the Venom Voodoo generated a dBA level of 38.9, which is easily tolerated. Once we increase the speed of the these fans the noise level raises considerably. With the fans running at 1900 RPM they registered 51.4 dBA on our digital sound level meter. Quite painful really.
