Full textClassroom acoustics deal with spatial prerequisites for sound propagation, where good speech audibility is important for the well-being of students and teachers and provide opportunities for good learning environments. Cognitive abilities as memory functions are also influenced by sound environments, where lower background noise levels and shorter reverberation times are advocated by research and acoustical performance criteria for classrooms. Background noise levels, reverberation time T20 and room response C50 can together provide a picture of a good sound environment for classroom learning. In this survey, five classroom sound environments have been evaluated and questionnaires have been used to investigate the subjective experiences of pupils and teachers in these sound environments during current investigated lessons. There has been no clear correlation between acoustic data and subjective experiences of the audio environment from this survey. However, the survey has obtained acoustic measurements from the current classrooms and especially two of the classrooms have been found to be substandard in comparison with the guideline values of reverberation time from standards.

Full textThe vowels of the basque dialect of barkoxe in the county of zuberoa are studied from a specially built corpus, and using experimental acoustic phonetics. Sentences from the corpus have been recorded by seventeen local speakers, and then have been digitalized. Acoustic characteristics of those of the vowels which will be analysed will be calculated using + ahotsa ;, a specialized software. The study starts from the first sub-corpus, made of [p], [t], [k] consonantic environments, and is then completed by the second sub-corpus, namely, [b], [d], [g] and [c] consonantic environments. The analysis is made dividing the stressed occurrences from the non stressed ones, and then comparing them. For each case, vowel dispersion fields and acoustic triangles are built, at first for each speaker, then for all male speakers, for all female speakers, and lastly for all the speakers together. In addition, existing links between acoustic parameters are considered : first, linear correlations between acoustic characteristics are searched, and then vowel after vowel, the influence of stress on each of the acoustic parameters we are working on is statistically analysed. As a conclusion of this work on the characteristics of vowels of the basque dialect of zuberoera, all the results we have found are obviously commented. They are also compared with those results and comments that were found in the review of subject related litterature that we presented as a first step

Full textDetta arbete söker svar på om det är realistiskt att använda akustiska metoder för att i stor skala sortera ut tungmetaller från pump-muddrat sjöbottensediment. Utgångspunkten har varit att materialet ska genomgå hydrotermisk karbonisering (HTC) innan akustisk behandling. Ett antal vetenskapliga rapporter har studerats för att kunna förstå var forskningsfronten är, gällande att manipulera små partiklar i vätska med hjälp av högfrekvent ljud (ultraljud). Diskussion har hållits med experter på ultraljud, HTC och kemisk analys. Avslutningsvis har möjligheten att avlägsna tungmetaller ifrån HTC-behandlat material med hjälp av ultraljud evaluerats, baserat på teoretiska möjligheter, jämförelser med ett urval av liknande studier, och begränsade mätningar av egenskaper hos materialet. Förutsättningarna för praktiska experiment, som skulle kunna bevisa eller motbevisa denna möjlighet, har utforskats. Möjligheten att skala upp processen har diskuterats.

Full textThis report is a part of the one year master programme in Civil Engineering - Sustainable Built Environment. The report focuses on the acoustic properties of a prefabricated composite floor slab built with three main components; a thin concrete slab, timber beams and a cross laminated timber slab. Initially a study of the environmental impact of the building industry, and how more effective use of building materials can contribute to a more sustainable development, is made. A study of how different sounds affects people is made and also how this is considered by different requirements in the Swedish building regulations to reach a more sustainable built environment. The studied floor slab is part of a cooperation project between Hedareds Sand & Betong AB, AB Fristad Bygg, The University of Borås and SP Technical Research Institute of Sweden and the sound tests are made in an acoustic laboratory at SP in Borås. The results of the tests are evaluated and are compared with the building regulations as well as with other types of floors. A study of the types of complements that are needed to reach the requirements in the building regulations is made.

Full textDetecting noise levels explains a lot in urban areas such as noise levels, number of shots, and number of collisions. In this project, a sound detector is installed that communicates via LoRa, Long Range when the sound exceeds a threshold value. The sound detector is implemented as a stand-alone module consisting of three existing modules. The modules used in the project include Lopy4 with Expansion Card 3.1, GPS module, and Sound sensor. The sound level, battery level, coordinates, date, and time are transferred via LoRa to a gateway and on to The Thing of Network, TTN website, and at the same time data is saved locally in an SD memory card when the sound exceeds a threshold. The threshold can be modified according to the user's wishes.

Full textThe purpose of this report is to find out how an acoustic measurement is done. The measurement results are used to see if the facility meets the requirements of the different parameters for the tenant's use. The parameters are reverberation, clarity grade for speech and music. To make such a measurement requires both theoretical and practical knowledge in acoustics and technology. We read a lot of literature on the topic acoustics and how to conduct an acoustic measurement. We made a number of measurements in different rooms at the school premises we chose to measure in the concert hall and studio. We measured reverberation time, clarity grade for speech and music. After the measurements were carried out, we got the results we expected to get. Because these facilities are built of high quality and meets the requirements of ISO source [11].

Full textThis study highlights the intensity and the extent of sound levels produced by a so called floating floor. The study has closely observed floor constructions made of Platon mat in order to detect the acoustic factors and how they are manifested when stepping on the floor. The study also compares the results of step- and drum sound levels with Granab constructions, another type of floating floor, as well as how the Platon construction stands in relation to the statutory guide values. This study has focused on how the sound from a Platon floor is perceived in an objective and a subjective perspective, because in some cases measured values do not correspond to the actual experience. Measurements that have been carried out give an idea of how to design floors and what type of material should be used to obtain the most favorable sound level possible. Overall, this study shows that the design of the floors can, to a large extent, minimize step- and drum sounds. This knowledge can be of great use when designing a floating floor since it has been shown that high sound levels in the lower frequencies affect, among other things, our abilities of learning and concentrating.
