Model NO.: ST-SG4040
In motor noise testing, acoustic chambers and acoustic boxes are indispensable. Acoustic chambers provide a controlled, quiet environment that minimizes external noise interference, enabling accurate measurement of motor - generated noise. Acoustic boxes, meanwhile, are used to enclose the motor, further isolating it from ambient sounds. This isolation ensures that the measured noise precisely reflects the motor's performance, helping engineers identify and address noise - related issues effectively, thus enhancing the quality and reliability of motors.
