  1. 6. Acoustic properties of a 5G Telecom Equipment Shroud Design for Noise suppression

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : David Andersson; [2021]
    Keywords : Acoustics; 5G; Shroud; Telecom; Noise reduction; Akustik; 5G; Kåpa; Teleutrustning; Ljudisolering;

    Abstract : As technology moves forward it has a tendency to consume more and more power that needs to be cooled by bigger and louder fans, this is especially true for the new generation of 5G radio equipment. This Master thesis is a collaboration with Ericsson and attempts to construct a shroud for containing a number of 5G radio units whilst attenuating the fan noise of the units as effectively as possible.

  3. 7. Acoustic Prediction Methods for Rocket Flame Deflector Design

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : FREDRIK RANOW; [2021]
    Keywords : Flame deflector; Launch pad; Estimation methods; Acoustics; Reflectivity; Diffraction; Directivity; Flamdeflektor; Uppskjutningsplattform; Uppskattningsmetoder; Akustik; Reflektivitet; Diffraktion; Direktivitet;

    Abstract : The aim of the project behind this report is to gain an understanding for the design criteria of launch pad flame deflectors used for launching rockets. This report presents an overview of the underlying phenomena, and then tackles the issue of estimating noise levels that come about during lift-off. READ MORE

  4. 8. What's Next in Sustainable Acoustic Materials?

    University essay from Lunds universitet/Innovation

    Author : Klas Hellqvist; Anna Andersson; [2020]
    Keywords : Sustainability; Acoustics; Materials; Sound Absorption; Technology and Engineering;

    Abstract : As industries have begun to rethink the way they design, make and dispose of products for the purpose of sustainable development, manufacturers of acoustic products have been slow off the mark. The majority of acoustic products are still made of primarily virgin material made from petrochemical resources, which have a significant impact on the environment. READ MORE

  5. 9. Attenuation AND awareness? : Designing a method for measuring accuracy and certainty of sound identification when wearing a HPD

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Markus Ahlberg; [2020]
    Keywords : Industrial design engineering; method design; sound identification; situational awareness; hearing protection devices; noise pollution; level-dependent function; Teknisk design; metoddesign; ljudidentifikation; situationsmedvetenhet; hörselskydd; buller; bullerföroreningar; nivåberoende funktion;

    Abstract : Noise pollution is widespread in today’s society, from traffic to industrial sources, and many people are confined to unhealthy acoustic environments through their employment. When noise cannot be eliminated at the sound source, the protective measure is usually to equip the employee with hearing protection devices (HPDs), e.g. READ MORE

  6. 10. Evaluation of OSTE-hybrid materials for acoustophoresis applications

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Elin Forss; [2020]
    Keywords : Acoustophoresis; off-stoichiometry-thiol-enes; OSTE; microfluidics;

    Abstract : This project aimed at exploring new hybrid materials to be used for acoustophoresis applications. Acoustophoresis can be used to manipulate particles inside a microfluidic channel by creating ultrasound standing waves within the channel [1]. This can be used for cell separation [2] or trapping of particles [3]. READ MORE
