It can be used as a means of communicating noise impact to stakeholders, it provides feedback to the noise analyst regarding the system under design, and it serves as an integral element of perception-influenced design. This talk first discusses the building blocks for auralization including source noise synthesis, propagation and sound reproduction. Next, a new auralization framework with linkages to system noise prediction is introduced. Finally, auralizations of future air vehicles including urban air mobility (air taxi) concepts, next generation commercial transports, and small unmanned aerial systems are discussed. <br /><br />Dr. Rizzi joined NASA in 1989. He is the driving force behind the Perception-Influenced Design effort to develop revolutionary tools and methods for low noise design of transformative air vehicles. He and his team support several NASA and industry projects, including the NASA Revolutionary Vertical Lift Technology, Convergent Aeronautics Solutions, Transformational Tools and Technologies, and Environmentally Responsible Aviation projects. He is recipient of the 2015 NASA Exceptional Service Medal for &quot;sustained and exceptional contributions to the acoustics discipline.&quot; He is an Associate Fellow of the AIAA and currently serves as Vice-Chair of the AIAA Aeroacoustics Technical Committee. He received his BS in Aerospace Engineering from the State University of New York at Buffalo, and his MS and Ph.D. in Aeronautics and Astronautics from Purdue University.http://www.chalmers.se/sv/institutioner/ace/kalendarium/Sidor/Frederik-Rietdijk.aspxhttp://www.chalmers.se/sv/institutioner/ace/kalendarium/Sidor/Frederik-Rietdijk.aspxFrederik Rietdijk<p>SB-L516, Sven Hultins gata 6</p><p>​Auralisation of airplanes considering sound propagation in a turbulent atmosphere</p><div>​</div> <h6 class="chalmersElement-H6">Abstract:</h6><p>Aircraft noise is a major issue in urban areas. Due to a rising level of urbanisation and the continuing growth of air traffic more people are exposed to aircraft noise than ever. Methods currently used for assessing the<br />impact of aircraft noise on humans consider mostly energetic quantities, and not the dynamic character of the sound. Therefore, in order to obtain a more accurate picture of the impact of aircraft sound it may be helpful to assess how the audible sound is perceived.</p> <p><br />Auralisation is a method for rendering audible sound fields and may be used to create audible aircraft sound. A tool was developed to auralise the sound of jetairplanes and consists of an outdoor sound propagation model and an emission synthesiser. The emission synthesiser computes an emission signal consisting of tonal<br />components and broadband noise. The spectral components vary over time and take into account directivity.<br />An inverse propagation model was developed to compute back from a receiver to source in time-domain. An automated procedure was developed to extract features from the resulting signal. These features were then used to directly synthesise the emission as function of time, and this signal was propagated to the original<br />receiver resulting in an auralisation that should reproduce the recording it is based on.</p> <p><br />To validate the auralisation tool, a listening test was conducted where participants were presented with recordings and auralisations and had to rate their similarity. Results indicate that differences exist between the auralisations and recordings. Improving the synthesis of the blade passing frequency is expected to improve the similarity between auralisations and recordings.</p> <p><br />Finally, fluctuations can typically be noticed when listening to sound from a distant aircraft, and one cause of these fluctuations is atmospheric turbulence. A computationally fast algorithm was developed to take into account the amplitude and phase modulations that arise as the sound propagates through the turbulent atmosphere. According to the author the method results in improved plausibility of the auralisations.<br /></p> <div> </div> <div><div><h6 class="chalmersElement-H6">Keywords:<span> </span>Atmospheric turbulence,Aircraft noise, Auralisation, Outdoor sound propagation<span></span></h6></div></div>http://www.chalmers.se/sv/styrkeomraden/samhallsbyggnad/kalendarium/Sidor/Rattvis,-gron-och-tillganglig-stad.aspxhttp://www.chalmers.se/sv/styrkeomraden/samhallsbyggnad/kalendarium/Sidor/Rattvis,-gron-och-tillganglig-stad.aspxRättvis, grön och tillgänglig stad: Mistra Urban Futures Göteborgskonferens 2017<p>Världskulturmuseet, Södra Vägen 54, Göteborg</p><p>​Hur blir en stad rättvis och samtidigt grön och tillgänglig? Vad är egentligen en rättvis stad? För vem och ur vems perspektiv?  Under Mistra Urban Futures Göteborgskonferens 2017 den 5 oktober på Världskulturmuseet hoppas vi kunna inspirera och vrida på invanda tankar och idéer.</p>​<br />Frågor kring hållbarhet och social rättvisa kommer allt högre på agendan för världens länder! Inte minst inom EU diskuteras dessa frågor livligt och i november 2017 står Göteborgs Stad värd för ett EU-toppmöte kring rättvisa jobb och tillväxt. <br /><br />Men jobb och tillväxt existerar inte i ett vakuum utan i relation till alla hållbarhetsdimensioner och i relation till de städer där jobb skapas och tillväxt sker. Så hur blir då en stad rättvis och samtidigt grön och tillgänglig? Vad är egentligen en rättvis stad? För vem och ur vems perspektiv? <br /><br />Under Mistra Urban Futures Göteborgskonferens 2017 den 5 oktober på Världskulturmuseet hoppas vi kunna inspirera och vrida på invanda tankar och idéer. Vi hoppas vi kan bidra till perspektiv och inspiration som också kan leva vidare in i samtalen under EU-toppmötet.<br /><br />Välkommen!<br /><br /><a href="http://www.mistraurbanfutures.org/en/content/goteborgskonferens-2017"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Mer information och anmälan</a>http://www.chalmers.se/sv/styrkeomraden/transport/kalendarium/Sidor/Teknologidagene.aspxhttp://www.chalmers.se/sv/styrkeomraden/transport/kalendarium/Sidor/Teknologidagene.aspxTeknologidagene 2017<p>Clarion Hotel &amp; Congress, Trondheim, Norway</p><p>​Statens vegvesen er en sentral aktør for å få mer grønn transport i Norge og inviterer til fire dager spekket med interessante fagkonferanser, norske og internasjonale foredragsholdere, lynforedrag, debatter og sosiale sammenkomster.

This event will offer the opportunity for scholars from Europe, as well as from around the world, to contribute to the exchange of experiences, ideas and knowledge regarding planning in the 21st century, in particular in relation to the congress theme: MAKING SPACE FOR HOPE.</p><div>​</div> <div>Planning is one of the activities – on different levels and in different contexts – striving for better futures. We live in dark times – climate crisis, economic regression, war and conflicts of political, ethnical and religious reasons. What used to be unrecognized by traditional planning debates can be useful to respond to contemporary planning problems. In-between spaces, insurgencies and untold stories can be rethought and re-explored to energize planning debates and practice. The challenges should be considered as triggers for transformations to a sustainable future. Planning should contribute to MAKING SPACE FOR HOPE.</div> <div><br /></div> <div>AESOP Annual Congress is one of the world's largest spatial planning conferences that will now be held in Gothenburg (2018).
