When a public school decides that every child deserves to hear good music

"A music practice room so reverberant that children can't hear themselves practice — does that even count as practicing?"

"An auditorium where children perform on stage, but those in the back rows only hear echoes"

This is what Srisawat School, under the Ministry of Education, chose to change, and this is the story of an investment that is not just about sound, but an investment in the future of every child.

📖 The Project Story — When a school saw what many overlooked

Srisawat School is an educational institution under the Ministry of Education that emphasizes comprehensive child development, not just academics, but also artistic and musical skills, which science has proven to significantly enhance children's brain development and emotional intelligence.

But there has always been one thing silently hindering music learning —

Music practice rooms that were so reverberant that children couldn't clearly hear themselves play, and an auditorium where echoes interfered, preventing every performance from being conveyed to the audience as it should.



These problems had existed for so long that many thought they were "normal for schools" — But it shouldn't be normal.

🎵 Two Spaces, Two Challenges — But One Solution

• Music Practice Room — A space where children must hear themselves clearly

A good music practice room is not just a quiet room, but a room that provides accurate sound information to the player.

When children play a note and hear an echo, their brains get confused between the sound they produced and the reflected sound. This slows down the development of listening skills and playing accuracy, without either teachers or students knowing why. It's not because the children lack talent, but because the room doesn't help them develop to their full potential.

• Auditorium — A space where every child deserves clear applause

An auditorium is a stage where children stand and present themselves to the world, whether it's for speeches, plays, or annual music concerts.

But when echoes interfere and make it difficult for the audience to understand, the efforts of all the children who practiced for months are not appreciated as they should be. That's not just a sound problem, but a problem of self-confidence being unintentionally undermined.

🛠 The Chosen Solution — Trandar ZIVANA Wall System in Every Area

The Trandar team chose the ZIVANA Wall System as the solution for both areas, with clear reasons.

✅ Trandar ZIVANA Wall System — Truly absorbs echoes and looks good in school areas too

The ZIVANA Wall System is an acoustic wall system designed to absorb echoes in the frequency range of speech and music, ensuring both the music practice room and auditorium have an appropriate Reverberation Time for their use.

What makes ZIVANA particularly suitable for a school environment is its durability and safety for spaces used by children, as well as its clean and orderly appearance that blends in with the educational institution's surroundings, without looking strange or overly prominent.

📐 The Impact of Good Sound on Learning — What science says but no one talks about in Thai education

Research from various institutions worldwide has found that sound quality in classrooms directly impacts educational achievement.

Children who study in highly reverberant rooms show 15-20% less ability to comprehend content than children in rooms with good acoustics. This effect is particularly severe in children learning language or musical skills, as both require clear and accurate hearing as a foundation.

Srisawat School chose not to let that 20% ceiling hinder children's growth any longer.

✨ The Result — Sound Changes, Room Changes, Children Change

After installing the Trandar ZIVANA Wall System in the music practice room and auditorium, the changes were immediately clear.

In the music practice room, children began to hear themselves more clearly. Teachers could provide more accurate feedback because they heard students' sounds as they truly were. Each practice session became more efficient in the same amount of time.

In the auditorium, the voices of performers and musicians reached every seat in the audience clearly. The next performance after the installation became a completely different experience for both performers and audience members.

"Every child has their own talent. Our duty is to create a space where that talent can be fully expressed — and good sound is the foundation of everything."
