Abstract
A sound isolation testing system and a sound isolation testing method are provided. The sound isolation testing system is adapted to test a product having a sound hole, and includes a detection device and a gas pressure detector. The detection device includes a gas cover, and the sound hole is sealed by the gas cover. The gas pressure detector is electrically connected to the detection device. The gas pressure detector determines a gas pressure change rate in the sound hole, and calculates the sound isolation value of the product according to the gas pressure change rate.
