  1. 1. Correlation between measured and perceived impact sound in schools

    University essay from Luleå tekniska universitet/Träteknik

    Author : Anton Burwall; [2022]
    Keywords : Acoustics; Impact sound; Impact sound insulation; Walking sound; Walking sound annoyance; Wood; Cross-laminated timber; CLT; Schools; Perception;

    Abstract : This project investigated the correlation between measured impact sound insulation and perceived walking sound annoyance in schools. The correlation was tested by performing standardized impact sound insulation measurements for different floor structures and comparing the measurement results with subjective perception of recorded walking for the same floor structures.

  4. 3. Utilization of Rubber and Plastic Waste as  A Partial Replacement of Aggregate for  Improved Sound Insulation

    University essay from Luleå tekniska universitet/Arkitektur och vatten

    Author : Nooralhuda Chabuk; [2022]
    Keywords : concrete; rubber; plastic. PET; insulation.;

    Abstract : Globally, billions of tons of rubber and plastic waste are produced annually, and because these wastes degrade so slowly (about 450 years for plastic bottles and 80 years for tire rubbers), they are extremely difficult to dispose of. As a result, utilizing these wastes directly in building materials can significantly reduce the environmental load while also increasing the sustainability of the building material. READ MORE
