Vehicle–road interaction for interior noise measurement and evaluation
Nowadays, one of the most valuable criteria of vehicle quality assessment is based on acoustic emission levels. A vehicle is judged comfortable depending on the noise levels transmitted inside. Consequently, there is a general attention to the design criteria aimed at improving the structural acoustic behaviour, to comply with the increasingly restrictive ergonomic standard. Therefore, it is ...

Accelerating with Bugatti - Case study
When the Bugatti Owners’ Club established itself in 1929, its members didn’t really have too much to worry about when it came to issues such as road congestion and noise. But just as cars have moved on with the times so has the Club. The Club applies a strict noise level threshold for competing cars at their renowned meetings on Prescott Hill near Cheltenham, Gloucestershire. Cirrus ...

Measuring Noise Outdoors
In recent weeks, we have received a number of calls asking for our recommendations on semi-permanent systems for measuring noise outdoors. Well, if you are specifically looking for a data logging integrating averaging sound level meter to undertake your environmental, vehicle and outdoor noise measurements, we would suggest that you take a look at the Pulsar Quantifier range. Pulsar ...

On a simple technique to measure the airborne noise in a car interior using substitution source
From various methods of measuring noise in a motor vehicle, a technique to separate the airborne and structure–borne noise is of interest as an important measure to improve the noise control treatment. This paper proposes a simple technique to measure the contribution of the airborne noise in a vehicle cabin using substitution source method. A cone loudspeaker was used as the substitution source ...

Characterisation of multiple interior noise metrics and translation of the voice of the customer
Several metrics represent noise characteristics such as engine idle, acceleration, and rough and smooth road noise because many factors affect vehicle noise. Engineers have to juggle several metrics to satisfy heterogeneous customer needs. All important design variables, which are often well correlated, should be included in translating the Voice Of the Customer (VOC) because the noise ...
