NOISE ABATEMENT ON DIESEL LOCOMOTIVES. FAN NOISE

The properties and constructional characteristics of different types of ventilators with respect to noise-production are discussed. It is shown that noise produced by ventilators can be suppressed only to a limited extent (Chapter 3). However, provided that it is designed with care, every ventilator can be effectively damped (Chapters 5 and 6). Since each application, involving certain constructional, thermal and functional requirements, demands a particular ventilator (Chapter 4), efforts should be made to develop quiet ventilation systems by appropriate dimensioning. Silencers provide a simple means of reducing the noise of ventilators. Space for these should be allowed for when designing. Data on the fan noise of modern locomotives is contained in a supplement to this report, and is used as far as possible as a basis for establishing general standard values.
