Повний текст джерелаI ett samhälle där buller håller på att bli ett stort hälsoproblem och en ekonomisk belastning, är ljudutsläpp en allt viktigare aspekt för fordonstillverkare. Då ungefär en fjärdedel av den europeiska befolkningen bor nära vägar med tung trafik, är åtgärder för minskat trafikbuller i stadsmiljö en hög prioritet. Introduktionen av elfordon på marknaden och behovet av ljudsystem för att varna omgivningen kräver också ett nytt synsätt och tekniska angreppssätt som behandlar bullerproblemen ur ett bredare perspektiv. Buller bör inte längre betraktas som en biprodukt av konstruktionen, utan som en integrerad del av den. Att utveckla mer hållbara marktransporter kommer att kräva en bättre förståelse av det utstrålade ljudfältet vid olika realistiska driftsförhållanden, utöver de nuvarande standardiserade kraven för förbifartstest som utförs i ett fritt fält. En viktig aspekt för att förbättra denna förståelse är utvecklingen av effektiva numeriska verktyg för att beräkna ljudalstring och ljudutbredning från fordon i rörelse. I denna avhandling föreslås en metodik som syftar till att utvärdera förbifartsljud som alstras av fordons akustiska källor i en förenklad stadsmiljö, här med fokus på strömningsgenererat ljud. Även om det aerodynamiska bullret är fortfarande en liten del av de totala bullret från vägfordon i urbana miljöer, kommer denna andel säkerligen att öka inom en snar framtid med införandet av tysta elektriska motorer och de bullerreducerande däck som introduceras på marknaden. I detta arbete presenteras en komplett modellering av problemet från ljudalstring till ljudutbredning och förbifartsanalys i tre steg. Utgångspunkten är beräkningar av strömningen kring geometrin av intresse; det andra steget är identifiering av ljudkällorna som genereras av strömningen, och det tredje steget rör ljudutbredning från rörliga källor till observatörer, inklusive effekten av reflektioner och spridning från närliggande ytor. I det första steget löses flödet genom detached-eddy simulation (DES) för kompressibel strömning. Identifiering av ljudkällor i det andra steget görs med direkt numerisk lobformning med avfaltning med hjälp av linjärprogrammering, där källdata extraheras från flödessimuleringarna. Resultatet av detta steg är en uppsättning av okorrelerade akustiska monopolkällor. Steg tre utnyttjar dessa källor som indata till en ljudutbredningsmodel baserad på beräkningar punkt-till-punkt med Greensfunktioner för rörliga källor, och med en modifierad Kirchhoff-integral under Kirchhoffapproximationen för att beräkna reflektioner mot byggda ytor. Metodiken demonstreras med exemplet med det aeroakustiska ljud som genereras av ett NACA-luftintag som rör sig i en förenklad urban miljö. Med hjälp av denna metod kan man få insikter om ljudalstringsmekanismer, om källegenskaper och om ljudfältet som genereras av källor när de rör sig i en förenklad stadsmiljö.

Повний текст джерелаThe goal of this work is the development of tools that allow simulating through headphones the psychoacoustic effect of sound sources moving in space, by the auralisation of the original monophonic signals. Although binaural auralisation can be implemented using variations in delays (called ITD interaural time difference) and in intensities (called ILD interaural level difference) among channels, better psychoacoustic results can be achieved using digital filters known as HRTFs (head related transfer functions). A HRTF inserts in the monophonic signal information that allow the auditory system to perceive this signal to be as if coming from a specific direction, which is unique for each single HRTF. Thus, to position a static sound source at a specific direction, filtering the original signal with the HRTF from the desired direction would be enough. Nevertheless, if it is desired that the sound source moves in a continuous trajectory, an infinitely large amount of filters would be necessary. Since they are usually obtained by measurements, such an arbitrarily large amount of them is not available. In this case, HRTF interpolation techniques that generate intermediary filters must be used. This work presents three new HRTF interpolation techniques in order to auralise moving sound sources: the triangular interpolation, a linear interpolation technique based on the VBAP amplitude panning technique; the discrete movements method, an extremely efficient technique that exploits the auditory systems limitations in perceiving very small changes in direction; and the spectral interpolation, that alters continuously the structures of the HRTFs to generate interpolated filters. Implementations of these techniques are discussed and numerical tests are also presented.

Abstract The Phenomenon of the sound field generated by a moving sound source has been investigated in the present work with two-part subject. The first part is to establish the mathematical model and the corresponding numerical scheme; the second part is to employ the established numerical scheme in practical acoustic problems. In order to establish the mathematical model, a novel governing equation is derived and it can be viewed as a modified Ffowcs Williams-Hawkings equation (FW-H-equation). The major characteristic of the novel governing equation is to include the interior and the exterior domain. In addition, the acoustic position vector, the quality describes the relations about the distance and the direction between the observer and the sound source, is represented for applying to the condition of the sound source moving with variable speed. As to the solution of the governing equation, it is expressed in the form of the Surface Integral Formula (SIF) by convoluting the free-space Green’s function in time domain. Then, this SIF is used to numerical implementation in the concept of the Boundary Element Method in time domain (BEMTD). After establishing the numerical scheme and verifying the correctness of the calculating results, two acoustic problems were investigated for revealing the ability of the numerical scheme. The first case considers that a moving line source with variable speed. This case reveals that the restriction of the constant speed is released in the established numerical scheme. For the simulation results, it shows that the effect of the variable speed not only influenced the variation rate of the frequency modulation, i.e., Doppler effect, but also the time about the maximum acoustic pressure being observed. In addition, the rate of the amplitude variation is shaper than that in the constant speed case when the line source is approaching to the observer point. The second case investigates the binaural hearing perceived by a moving sound source. For understanding the weighting of the eventful cues about perceiving the direction and the speed of the moving sound source, the sound pressure at the entrance of the external ear canal was calculated by the established numerical scheme. Furthermore, the Hilbert Huang transformation (HHT) is used to find the instantaneous frequencies of acoustic signal. Results show that the Interaural Level Difference (ILD) and the frequencies shifting are eventful than Interaural Time Difference (ITD). The perceived loudness level will be larger in the motional case than that found in the stationary case. These engineering problems are shown that the acoustic properties are different for comparing with the sound field generated by a moving sound source and that by a stationary sound source. As to the analytical methodology developed in the present work, it turns out that it indeed can be used to simulate and analyze these acoustic problems whenever the sound source moves or not. Furthermore, some meaningful phenomenon relating to these problems then can be observed through discussing the calculating results.

Binaural hearing outperforms monaural hearing in both speech perception and sound source localization owning to benefit from head shadow and summation effects. Especially monaural hearing is lacking in benefits from head shadow and summation effects, the only mean to discriminate is volume and that highly decreases performance of listeners. Furthermore, in real environment, sound source may be moving, that is the issue will be discussed in this thesis. HRTF database is used to simulate the dynamic or static audio used in experiments. All subject are normal-hearing and target sound sources includes 1000Hz pure tone, Chinese sentences and Chinese sentences with SSN, all these three cases will used in Binaural hearing test and monaural hearing(left ear only and right ear only) so that the result of tracking different sound sources will be acquired and discussed. The results from 1000Hz experiment will be used to compare to other results as a test basis. Also, acquiring comparison of 1000Hz and Chinese sentences will be necessary as Chinese is a tonal language. And the experiment results do actually show the behavior of all subjects are quiet close unlike the result from sentences experiment. Then the results of sentences with SSN are more unpredictable, some further research may be necessary to get more information.
