Städtische Musikschule von Pinto

Die Städtische Musikschule von Pinto in Madrid musste die Akustik ihrer Einrichtungen verbessern, um ihre Schüler weiter zu motivieren und den Lehrern eine gesündere Arbeitsumgebung zu bieten.

More specifically, a multipurpose room as well as the entrance hall were both treated with Ecophon “Class A” absorbing acoustic solutions (Ecophon Akusto^TM Wall and Ecophon Gedina^TM E). This greatly reduced the reverberation time and improved the speech clarity, making it a more enjoyable experience for students, parents and teachers.

The school coordinator, Maribel Lliteras, was surprised after the intervention with the positive change in behaviour of the students once the intervention was carried out.

“Right now, explanations prior to activities can be given in the entrance hall without teachers having to stain their voice as the noise level does not increase”.

Acoustic measurements

The multipurpose room has a volume of approximately 300 m³ whereas the entrance hall has 480 m^3. Whereas the entrance hall is sparsely furnished, the multipurpose room is fully equipped with chairs, tables, shelves, etc. Regarding the linings, both spaces have the walls made of plasterboard, the flooring is ceramic tiles and the ceiling is a reflecting/non-absorbing ceiling.

The results of the reverberation time measurements carried out before and after the acoustic intervention, averaged through the different measurement and source positions, can be seen in the tables below.

Summary of average values of the reverberation time in both spaces.

	Entrance hall		Multipurpose room

Tmid [s]*	2,27	1,17	1,17	0,6
T [s]**	1,98	1,05	1,13	0,72

The sound levels were significantly reduced in both spaces. In order to gain further knowledge about how much the of both rooms, sound level measurements were made at different positions in both spaces to gain a more accurate understanding around how the sound levels are now controlled in these spaces. The sound pressure level reduction in the entrance hall is reduced by around 4dB and around 6dB in the multipurpose room.
