Investigation into the Acoustic Properties of the Newly Designed Plasterboard Structures with Acoustic Granulate and 6 Types of the Innovative Structure with Acoustic Granulate Installed in Buildings
Project Investigation into the Acoustic Properties of the Newly Designed Plasterboard Structures with Acoustic Granulate and 6 Types of the Innovative Structure with Acoustic Granulate Installed in Buildings. LLC Lorensa. Supervised by T. Janusevičius. Dates and deadlines: 2017.
Findings. The structures designed for sound insulation in buildings were created and complex investigations of their properties were carried out. The structures used rubber granules processed applying an innovative ozonation method. This type of granules had a larger surface arearather than conventionally treated rubber granules. The granules were glued together into conglomerates to receive rubber plates bigger in mass compared to conventional sound-absorbing materials, and therefore had better acoustic properties of absorbing low frequencies. With the help
of specific polymeric glue, rubber granular plates were glued to building materials possessing sound insulation properties thus determining the rubber granules, their fraction and plate density having the best acoustic properties.
Research on acoustic properties was performed in the noise cancellation chamber intended for investigating the acoustic properties of various materials and structures. Investigations into the noise reduction coefficient Rw and sound pressure level differences of the tested specimens (5
items) in the frequency bands from 50 Hz to 8000 Hz were performed thus suggesting an effective acoustic rubber granulation design.

Findings. According to the World Health Organization, lead is among the top ten chemicals that pose a major concern with regard to human health risks. Lead is a toxic metal, and its extensive use exacerbates environmental pollution and health problems in many parts of the world.
Population exposure to lead is the cause of about 0.6% of the world's diseases, especially in developing countries. Its use in products of various uses raises concerns about its effects on the environment and human health. The use of lead in the manufacture of protective seals has been known since ancient times, but because of lead as a dangerous substance, more and more countries refuse this kind of environmental seal. Lead protective seals in Lithuania are still widely used for sealing water, gas, electricity meters, freight wagons and warehouses. On average, 40% of lead seals are used in the transport sector, 40% in the utilities sector and about 20% in other industrial sectors. The impact of lead in sealing seals on the environment and the health of workers was analyzed and evaluated.
