  2. 2. Measurements, Analysis Techniques and Experiments in Sound and Vibration Applied to Operational MRI Scanners and in Remote Laboratories

    University dissertation from Karlskrona : Blekinge Tekniska Högskola

    Author : Imran Khan; Blekinge Tekniska Högskola.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Noise Control; Remote Laboratories; Sound and Vibration Measurements; Vibration Analysis; Vibration Transmission;

    Abstract : High quality noise and vibration measurements outside of a laboratory environment on real life structures and applications are not trivial. True boundary and operating conditions enforce unique challenges on the measurements. Measurements in hazardous situations such as high magnetic fields, and high temperature environments, etc. READ MORE

    Abstract : Ljud från grannar är ett återkommande problem för boende i flerfamiljshus. Problemen är generellt mer omfattande för de som bor i flervåningshus byggda i trä, en byggnadstyp som blir allt vanligare i Sverige. Många av de boende i trähus upplever även att störande vibrationer är vanligt förekommande i trähus. READ MORE

    Abstract : When the Swedish building regulations in 1994 allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, as well as wood being a plentiful resource in Sweden. However, complaints amid inhabitants are often reported due to nuisances caused by disturbing vibrations and noise propagating in the building. READ MORE
