SPATIAL ACOUSTICS


AND FOOTFALL NOISE A sub-discipline of acoustics, spatial acoustics concerns the behaviour of direct sound and reverberation in rooms and is influenced by the structural conditions. Construction acoustics, on the other hand, describe the transmission of sound between adjoining rooms through transmitting constructional elements. The generated noise is transferred to adjoining rooms by means of structure-borne sound transmission through the materials used for the ceilings, walls and piping, for example.


Undesirable noise sources therefore have to be minimised to achieve good acoustics. This means that the construction acoustics need to be optimised in such a way that footfall noise, for instance, is not transmitted from other rooms and so that unwanted noise emissions are prevented in the room itself.


This is why leading clients request finishing materials that have achieved a low emissions award, so they have comfort in the fact that the building is positively influencing their employees’ health and working contribution. The Blue Angel award is regularly required as a standard to ensure the products chosen are stable and healthy.


The floorcovering is crucial for a healthy indoor climate on account of its surface area. Compatible products such as rubber floorcoverings from nora systems should be chosen here since they do not contain any PVC, plasticizers (like phthalates) or halogens and thus contribute to ensuring that indoor air remains healthy. nora has taken one step further and offers their own low emission installation materials as well, precluding any harmful interaction between the individual components. All the system components are mutually coordinated, have optimised emission

nora rubber floor coverings help to reduce these annoying noise sources. On the one hand they achieve a footfall noise improvement factor of up to 20 dB, resulting in footfall noise from one room being reduced to an absolute minimum when transmitted to an adjoining room. On the other hand, permanently resilient floor coverings reduce noise emissions caused by footsteps or trolleys, suitcases or similar objects being rolled across the floor to a much greater extent than is the case with harder materials. Compared with stone floors, this can mean a reduction by up to 10 dB, and unwelcome noises that do not occur in the first place do not have to be absorbed.


HYGIENE AND


CLEANING More than a third of the population is susceptible to allergies, for instance to house dust. In contrast to carpeted floors, rubber floorcoverings are safe for allergy sufferers because they do not offer a breeding ground for allergy- inducing substances. Their dense, closed surface means that dirt and dust remain on the surface of the covering and are completely removed by the appropriate maintenance cleaning.


Since they are post-cured before they leave the factory, nora floorcoverings do not require coatings, stains are removable and floors are easy and economical to clean. Spilled liquids such as coffee, tea or juice can be easily mopped up. And in contrast to carpeted floors, spillages do not leave behind any stains or disagreeable odours.


DESIGN AND
