ABSTRACT:
To assist textile mills in complying with Government regulation of noise levels, a tunable noise suppression device or muffler is connected to the exhaust of the fiber collection box of a pneumatic spun fiber collection system of a spinning machine. The device is adjustable to reduce exhaust noise to an acceptable level while maintaining the necessary degree of suction in the fiber collection system. The noise suppression device has the ability to nullify the most predominant noise generating sound wave lengths and/or predominant noise frequencies through tuning, whereby it is unnecessary to construct various sizes and configurations of the suppression device for use on different textile machines which may possess differing predominant noise frequencies.
