1 ARCHITECTURE ACOUSTIC AT ELBSCHULE HEARING AND COMMUNICATION TRAINING CENTER, HAMBURG GERMANY ACOUSTIC DESIGN INTEGRATED IN RECONSTRUCTION AND ENERGETIC RENOVATION FOR CHANGE OF BUILDING USE

2 PROJECT INFORMATION HISTORY Hamburg International School was first establised in 1973 by Schlutz & Partner Architekten Company. It was primarily made of concrete steel frame and infill brickwork. In 1984, physical activity hall was built and in 1999 the school was expanded by a three-storey building, designed by Stoermer Architekten Company. PRESENT In cooperation with the acoustic engineer office Taubert und Ruhe GmbH, the transformation process of Hamburg International School was planned, focusing on learning with hearing-impaired students. The project started in 2011, which also involved physical activity hall, canteen and fire prevention measures in both renovated and newly built constructions. Commence: 01/2012 Complete: 07/2013 Type: Renovation, Change of use, Building for disabled people Gross floor area: 10,800 m2 Project Address: Holmbrook 20, Hamburg Architects: Acoustic Engineers: Source:

3 1. RECEPTION LOBBY The ceiling is decorated with sound absorbing panels in alternative positions. These are made of Knauf AMF ceiling-rafts, which effectively absorb noise and are resistant to heat and moisture level changes. There can be easily replaced when old and damaged. Picture: Top: Sound absorbing panels at lobby Bottom: Project engineers explaining about the functions of panels Purpose: - Sound reduction, noise prevention - Decoration - Reduction of ceiling height Material: Compressed mineral fiber Example:

6 2.CLASSROOM Classrooms are installed with gyps ceiling to reduce noise. White ceilings reflect light well. Light from LED lights saves electricity and does not cause glare. Besides, the back of the class, in opposing direction to teachers, are panels for sound absorption. This measure is great for big rooms where sound is often reflected. Walls behind teachers back help delivering sound evenly to both front and back seats. Picture: Ceiling: suspended ceiling with Gypsum boards Wall: Sound absorbing wall panels (gray) against the reflective sound. Purpose: - Sound insulation, Noise prevention - Decoration - Light Reflection - Preventing Echoes and optimize room acoustics Material: - Ceiling: Gypsum boards - Wall: Polyester Acoustic fleece panels 50 mm thick Example:

7 3. IT CLASSROOM Floor carpets help reduce echos from db. Notably, a reduction of 10 db gives a feeling of noise reduction by a half, which also reduces stress. No other Flooring material is better than carpet at sound insulation. The computer screens are placed under the table to allow better communication between teachers and students. Picture: Top: IT room Bottom: Grey sound absorbing wall panels Purpose: - Noise prevention - Slipping prevention Material: Carpet

8 MUSIC PHÒNG ROOM ÂM NHẠC Acoustic walls in different colors (red, black) are attached to the floor and ceiling, or free-hung on steel ropes. The combination with acoustic ceiling panels creates a pleasant acoustic atmosphere.

SOUND INSULATED ROOM This is a renovation project so the structure is maintained. 2-layer window it prevents the penetration of noise from the environment such as street noise. Also energetic solution for a higher isolation Purpose: - Noise preventing (external) - Warmth keeping

16 7. CANTEEN Sound absorbing painting/picture It is made from a textile surface and a special acoustic core to lower the reverberation and support people concentrate on communication and to create higher comfort. The painting is stretched on an aluminum frame and is flexible on size and color. Under the painting can be a polyester material or several also absorbing sound and make it high effective. Example:
