An industrial acoustic enclosure was designed and fabricated to attenuate the noise generated by the mechanical shaker. The enclosure panels had a high transmission loss with the use of a high mass septum, and its thickness was specially designed for this application. A high transmission loss was also designed for the door and window, which had special seals to prevent noise leakage. Ventilation within the enclosure was achieved with an intake and exhaust silencer. This unit was fully assembled prior to delivery, making the installation extremely convenient.
