   Abstract : Purpose: Formula E, the electric counterpart to Formula 1, has not achieved the same level of popularity among consumers. The purpose of this paper is to understand why Formula E has not been as successful as Formula 1 and the barriers to consumer adoption of Formula E. READ MORE

3. 2. Experimental Study of Installation Effects on Cooling Fan Noise

   University essay from KTH/Marcus Wallenberg Laboratoriet MWL

   Author : Yu-Yu Lu; [2021]
   Keywords : Electric vehicles; Cooling fan noise; Installation effects; Free-space measurement; Wall-mounted measurement; In-vehicle measurement; Spectral decomposition method; Tonality; Broadband noise level.;

   Abstract : Owing to the ever-changing developments of battery and electric powertrain, vehicle electrification is the trend in the future. Without the presence of a combustion engine, masking effect from it reduces and noises from other components become perceivable. Among all, the cooling fan is one of the major noise sources.

4. 3. 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.

5. 4. Attenuation of fan noise with passive methods : An experimental study in the implementation of a ducted fan inside the body of a blended wing body UAV

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Mustafa Kulbay; [2021]
   Keywords : ;

   Abstract : This report is about a novel approach to attenuation of fan noise in aerial vehicles, by way of implementing a ducted fan in the chassis of a four meter blended wing body plane. Three different one meter PVC pipes were used and their performances as silencers were tested by measuring the sound power level and calculating the insulation loss compared to a fan by itself.
