  1. 1. Standardized Test Methods in Over-the-Air Chambers for FCC Part 27

    University essay from Umeå universitet/Institutionen för fysik

    Author : Oskar Hellström; [2023]
    Keywords : ;

    Abstract : Base stations (BSs) are the cornerstone that enables wireless communications. In order for a new BS variant to be imported and sold in the US they are required to undergo electromagnetic compatibility (EMC) testing. This testing is necessary to obtain their Federal Communications Commission (FCC) certification. READ MORE

  3. 2. The effect of furniture on room acoustic parameters and its dependence on the sound absorbing properties of the ceiling

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Huong Nguyen; [2023]
    Keywords : Room acoustics; furniture; Sabine s formula; SEA model; sound absorption; sound scattering; reverberation time; speech clarity; sound strength; Technology and Engineering;

    Abstract : In ordinary public rooms such as classrooms and offices, the base line of acoustical treatment is an absorbent suspended ceiling. Due to the non-uniform distribution of the absorptive ceiling material, the scattering as well as the absorption properties of furniture will have a significant effect on room acoustic parameters such as reverberation time, speech clarity and sound strength.

    Abstract : As the automotive industry advances through technology integration, components are designed to operate at increasingly higher frequencies. Consequently, there will be an increasing demand for automotive electromagnetic compatibility (EMC) testing. READ MORE

  5. 4. Prediction of Reverberation Time in Office Spaces by Investigation of the Scattering Factor in Odeon

    University essay from KTH/Teknisk akustik

    Author : Viktor Söderlund; [2023]
    Keywords : Scattering Factor; Reverberation Time; Odeon; Sabine; Arau-Puchades; Spridningsfaktor; Efterklangstid; Odeon; Sabine; Arau-Puchades;

    Abstract : Accurate estimations of the reverberation time of furnished office spacesis essential as an acoustic consultant. A time efficient way to predict thefurniture’s effect is to investigate it by software modelling. The room acousticsoftware Odeon is suitable for doing this. READ MORE

  6. 5. Can a Dry Recording Treated with a Convolution Reverb in a Surround Sound Speaker System be Perceived as Maintaining the Same Degree of Naturalness as Real Recorded Reverberation?

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

    Author : Sophie Andersson; [2023]
    Keywords : ;

    Abstract : When recording classical instruments, access to a physical space of acoustic properties associated with classical music might not always be available. This study seeks to investigate if classical music recorded in an environment with a short reverberation time can be treated with an impulse response from a concert hall and still maintain the same sense of naturalness.
