Presentation

The Unió Musical de Llíria, of which Her Majesty Queen Sofía is the permanent honorary president, is a non-profit organisation whose aim is to promote, encourage and disseminate musical education and culture. For all these reasons, the Unió carries out all kinds of activities that promote musical, educational, cultural and artistic aspects of leisure.

It has a hall dedicated to musical education, which is also used as an auditorium. At present, the acoustic conditions of the hall do not meet the standards required to carry out the activities for which it was designed.

In order to remedy the existing acoustic deficiencies, we are carrying out an acoustic study of the current conditions in order to determine the necessary corrective measures that will allow us to achieve our objective.

The materials used in the construction of the venue do not allow for adequate acoustic control. There is a varnished wooden floor, smooth painted walls, a ceiling with insufficient absorptive properties and several windows.

The hall is used for individual and group rehearsals of various musical groups. The acoustics of the room should be adjusted to take these particularities into account.

We measure the reverberation time of the room to determine whether it is suitable for the type of activity that takes place during rehearsals.

As you can see from the graph on the right, the average reverberation time is 1.9 seconds.

According to DIN 18041 ‘Room acoustics – Requirements, recommendations and planning guidance’, the recommended reverberation time is in the order of 0.8 seconds.

It will therefore be necessary to take corrective measures in the room to adjust its acoustic parameters.

The materials used in the construction of the venue do not allow for adequate acoustic control. Varnished wooden floor, painted smooth walls, suspended ceiling with insufficient absorbent characteristics and several windows.

The room is used for individual and group rehearsals of different musical groups. The acoustics of the room must be adjusted to take these particularities into account.

Thanks to 3D calculation tools, we were able to evaluate different options to determine the combination of materials that would allow us to meet the recommendations of the standard.

After several tests, adjusting the arrangement of the different acoustic materials, we arrived at this consensus solution:

  • Replacement of the existing suspended ceiling with our Acustec-N19 acoustic absorption panel.
  • Installation of 4 Acustiart acoustic islands in the ceiling.
  • Mounting of 10 Acustiart acoustic panels on a wall.
  • Laying of 34m2 of Acustiforo-TP16 perforated wood with air chamber filled with Acustifiber acoustic absorbent material.
