IFSTTAR - Institut Franais des Sciences et Technologies des Transports, de l'AmŽnagement et des RŽseaux

IFSTTAR is a public research institute with more than 450 permanent staff located mainly in Paris, Lille and Lyon (Head Office). Since 1970, IFSTTAR has considerable experience of research activities in the field of environment particularly at LTE (Transport & Environment Laboratory). IFSTTAR-LTE has been involved in the field of transportation noise for many years. LTE addresses not only noise emissions (measurement, modelling etc) from different means of transport (cars, trucks, trains, aircrafts) but also perception and annoyance issues: socio-acoustic surveys (field study) as well as experiments in laboratory (lab study).

Role in COSMA

IFSTTAR will contribute to the COSMA project (WP2) by addressing:

  • perception of preferred aircraft sounds by participating in aircraft sound synthesizer listening tests in laboratory (task 2.3);
  • noise annoyance by participating in laboratory studies and in a combined field and laboratory study in order to address the transferability of the laboratory results to real life conditions (task 2.2). Methods and tests specified and coordinated by IFSTTAR will be harmonized with those of field studies (task 2.1.).

PEDECE - Projecto, Empreendimentos, Desenvolvimento e Equipamentos Científicos e de Engenharia

PEDECE is an SME founded in 2000 that works active in aeronautical and space science and technology. Participation in aeroacoustics EU projects: Helinoise, Helishape, Friendcopter; Asanca I and II; Acoufat; Snaap, Apian; Enable; Jean; Silencer; Rosas, Nacre; Sefa, Cosma; X-Noise, X2-Noise, X3-Noise, X-Noise EV; Activity in flight dynamics, includes the EU/ESA/EUROCONTROL projects; Amaks; Efedal; S-wake; Nefa; Vela; Nacre; Flpp. Other areas of activity include atmospheric and space environment, plasma flows, astrophysics, and mathematical methods.

Role in COSMA

The role of PEDECE in COSMA is to model the changes in noise characteristics between emission by an aircraft and sound reception by an observer on the ground. Extensive listening tests with a variety of subjects from several nationalities show that the vast majority distinguishes between the 'original' aircraft sounds and airport 'recordings' near the ground. Since the airport sound synthetizer takes as inputs the original aircraft sounds, these must be modified to account for atmospheric propagation, in order to obtain 'airport noise' that appears realistic to test subjects.

SASS - SASS acoustic research & design

SASS has a long term experience in industrial target sound design particularly related to engineering sound quality. Acoustical design typically is closely associated with certain inherent physical properties of the sound source, e.g. the engine, such as time varying spectrum, RPM, speed, etc., and technical constraints in order to guarantee the feasibility of the process of implementation. Design validation typically comprises acoustic / psychoacoustic analysis in the laboratory and experimental judgment by subjects both in the laboratory and in the field. A robust and sensitive scaling technique for psychometric measurement in both experimental situations has been developed and validated in numerous studies.

Role in COSMA

In COSMA SASS will do the following tasks:

  • Together with LMS the database of source components models will be further extended.
  • SASS will develop a 3D auralization system to enhance the perception of the synthesized sounds.
  • Together with ISVR SASS will validate the output of the AIRPORT NOISE CLIMATE SYNTHESIZER.
  • Together with ITAP SASS will use an advanced non-linear analysis technique to correlate psychometric data to acoustical features.
  • To predict annoyance responses on the basis of acoustical data SASS will develop a Categorical and Regressive Tree (C&RT) decision model.
