    1. Impact sound reduction with TSS and RVK

    2. Stepsound Reduction with TSS and RVK Impact sound from stairs 2

    3. Stepsound Reduction with TSS and RVK Concerning only precast concrete stairs 3

    4. Stepsound Reduction with TSS and RVK Impact sound transmission from stairs = a great challange • Step sound is much more in focus, increasing interest • Most constructions can’t meet the new building standards • Step sound transmission from stairs to adjacent rooms • Reduces the qualety and the value of the building • Contractual liability for the contractor towards building standards 4

    5. Stepsound Reduction with TSS and RVK Step sound from concrete stairs without sound reducing efforts 5

    6. Stepsound Reduction with TSS and RVK Limit values from SINTEF Byggforsk in Norway 6

    7. Stepsound Reduction with TSS and RVK Highest levels for weighted impact sound • Livingroom 53 dB (48 dB for kl.B) • School 58 dB • Hospital 58 dB • Hotel 58 dB • Meeting room 58 dB • Office 63 dB 7

    8. Stepsound Reduction with TSS and RVK The principle for effective sound reduction 8

    9. Stepsound Reduction with TSS and RVK We developed and tested products for impact sound reduction over the last decade TSS 102 Masticord Rubberbox for wall Rubberbox for TSS 9

    10. Stepsound Reduction with TSS and RVK Tests showing us that there are some correlation between attenuation area and rubber hardness (Shore), and impact sound reduction. 10

    11. Stepsound Reduction with TSS and RVK Recommended solution for living apartments TSS 102 Reduction: 20- 25 dB 11

    12. Stepsound Reduction with TSS and RVK Recommended solution for: Schools, Hospitals, Hotels, Offices.TSS with vertical rubber flinch Reduction: 10-12 dB 12

    13. Stepsound Reduction with TSS and RVK Important Hints regarding step sound • Casting not bigger/wider than vertical rubber flinch • B=250 x H=200 • Elastic joint between landing and wall minimum 10mm • Tiles must not be in contact with the wall, minimum 10 mm joint ,base tiles forbidden 13
