Motor Racing Vehicles - Measurement Methods

1 Introduction

In order to regulate the noise impact of motor racetracks in the surrounding environment, the authorities have set limits for noise immission from racetracks. Due to the inherent difficulties concerning performance of reliable noise immission measurements at larger distances from the racetrack, prediction of the noise immission is a widely accepted method.

As input to the prediction models, a declaration of the noise emission of the racing vehicles is necessary. In order to predict a realistic noise immission, the noise emission must reflect the noise produced by the vehicles during normal racing conditions, i.e. it shall be immission relevant.

Further, periodical monitoring of the immission relevant noise emission for individual vehicles is necessary. This is done by the motor sport organisations at regular intervals during the season.

The purpose of this project is to develop simple and reliable methods for measurement of these noise emissions, i.e. a noise declaration and a monitoring method.
