ARCHITECTURE ACOUSTIC AT “ELBSCHULE” – HEARING AND COMMUNICATION TRAINING CENTER, HAMBURG GERMANY

ACOUSTIC DESIGN INTEGRATED IN RECONSTRUCTION AND ENERGETIC RENOVATION FOR CHANGE OF BUILDING USE

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, 22605 Hamburg

ARCHITECTURE ACOUSTICS

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.

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.

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: http://www.raum-akustiks.de/01_produkte/akustik-elemente.htm

Floor carpets help reduce echos from 20 – 50 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.

3. IT CLASSROOM

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.

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

Chair

Under each chair is a piece of porous sound absorber like from

foam to absorb sound.

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.
