  1. 31. The future noise mapping model in Sweden

    University essay from KTH/Teknisk akustik

    Author : Johanna Sturk; [2022]
    Keywords : Mechanics; Acoustics; Noise Emission; Noise Mapping Model; CNOSSOS; Nordisk beräkningsmodell; Mekanik; Akustik; Buller; Beräkningsmodell; CNOSSOS; Nordisk beräkningsmodell;

    Abstract : An extensive technological shift is currently taking place to mitigate climate changeand this trend is particularly noticeable in the transport sector. This is interestingfrom an acoustical perspective, since it changes the noise environment in society. READ MORE

  3. 32. Development and study of noise generation from propellers

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Anton Anton Dunström; Fredrik Skjernov; [2022]
    Keywords : Silent propellers; Propeller development; Noise generation; Skew angle; Blade Area Ratio; Openprop; NATO STANAG no. 1136; Swedish defense and Research Agency FOI ; James Fisher Defense.; Tysta propellrar; Propellerutveckling; Ljudskapande; Skevningsvinkel; Bladtäckningsarea; Openprop; NATO STANAG no. 1136; FOI; James Fisher Defense.;

    Abstract : Noise generation from underwater activities propagates into the marine environment.For marine vessels the propulsion system generates the most noise during itsoperations. Naval vessels that want to operate without being detected want to controlthe sound generating properties of the vessel. READ MORE

  4. 33. Bullernivåer i hästtransporter

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Linn Riddarhierta; Agnes Heinonen Persson; [2022]
    Keywords : Decibel; Buller; Häst; Stress; Transport; Väg; Hastighet;

    Abstract : Att transportera hästar kan innehålla flera moment där hästen kan känna stress eller obehag, inte bara vid lastning utan även under körning. På grund av detta säljs många hästtransporter på dagens marknad med fokus på att erbjuda god åkkomfort för hästen, men det beskrivs dock sällan om eventuell testad ljudisolering för att minska bullernivåerna.

  6. 35. Effects of water-vapor on the Ka/Q band Earth-space radio propagation channel

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Joar Marchner Brandt; [2021]
    Keywords : Attenuation Alphasat Water-vapor Oxygen Cloud ITU Budapest;

    Abstract : A higher frequency radio channel both increase the possible data rate and de- crease the required antenna size to efficiently transmit data. Higher frequency also introduce larger weakness to signal loss due to atmospheric effects. Al- phasat satellite conduct experiments for future use of higher frequencies by the Aldo Paraboni Payload.
