A noise survey has been conducted at five Norwegian airports. The two standard questions recommended by ICBEN were included in the questionnaire, and both the verbal and the numerical ICBEN response scales were used. The results were analyzed according to the CTL-method, which provides at convenient...

The noise characteristics of civil and military aircraft operations differ significantly. For example, the difference in flyover noise from a fighter aircraft and jet plane is easily heard. Civil traffic also tends to be spread out relatively evenly over a day, whereas military training operations c...

In the presence of ground reflections, the traditional methods for aircraft noise direction of arrival estimation based on the time differences between the microphones of a compact array lose accuracy in the vertical direction. With the aim of reducing this error, this work explores the use of direc...

Modelling and measurements go hand in hand. The developer needs to control results from his program against measurements to ensure that the model gives correct answers. The paper gives an overview of the development phase of NORTIM and the measurement campaigns that were conducted to ensure the...

The standard methodology used in traditional integrated aircraft noise models has recently been revised by ICAO, based on the recommendations in ECAC Doc 29, 3rd edition from 2005 [1]. The interim method for lateral attenuation proposed by SAE in 1981 [2] was thereby in use for 24 years! The basics ...

NORTIM, the program for calculation of aircraft noise propagation, has four main components: A calculation kernel, a project database, a master database, and a user interface. The latter is a tool where the user may combine operational input (from external sources) with data from the master database...
