摘要

Reduced sound levels are becoming an increasingly critical requirement in many evaporative cooling applications. This paper focuses on the technologies available to reduce sound levels in such instances. Technologies such as application of alternate fan designs, reduced rotational fan speed, attenuation to reduce fan noise, and attenuation and water silencing to reduce falling water noise will be presented. The magnitude of sound reduction for each technology will be illustrated. In addition, case histories will also be presented to illustrate the effect some of these technologies have in sound sensitive applications.
