When a public school decides every child deserves to hear great music

"A music practice room so reverberant that students can't even hear themselves play — can that really be called practicing?"

"An auditorium where students perform on stage, but audience members in the back hear nothing but muddy echoes."

These are the conditions Srisawat School, under the Ministry of Education, chose to change. This is the story of an investment that goes beyond acoustics—it's an investment in every child's future.

📖 Project Story — When a school notices what many overlook

Srisawat School is an educational institution under the Ministry of Education that prioritizes well-rounded child development—not just academics, but also arts and music skills, which science has proven significantly enhance children's brain development and emotional intelligence.

Yet, something has quietly hindered musical learning all along —

Music practice rooms plagued by reverberation, preventing students from clearly hearing themselves play, and an auditorium where distracting echoes prevent every performance from reaching the audience as intended.



These issues persisted for so long that many considered them "normal for a school" — but they shouldn't be normal.

🎵 Two Spaces, Two Challenges — But One Solution

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

A good music practice room isn't just quiet; it provides accurate acoustic feedback to the player.

When a child plays a note and hears a muddy echo bouncing back, the brain gets confused between the original sound and the reflection. Developing listening skills and playing accuracy slows down without either the teacher or student realizing why—not because the child lacks talent, but because the room doesn't allow them to fully develop.

• Auditorium — A space where every child deserves clear applause

An auditorium is the stage where children stand and present themselves to the world, whether through speeches, theatrical performances, or annual music concerts.

However, when disruptive echoes make it impossible for the audience to understand, months of hard work by the children fail to be properly recognized. This isn't just an acoustic problem; it's an unintentional blow to self-confidence.

🛠 The Chosen Solution — Trandar ZIVANA Wall System in All Spaces

The Trandar team chose the ZIVANA Wall System as the answer for both spaces for clear reasons.

✅ Trandar ZIVANA Wall System — Effectively absorbs echoes while looking great in a school environment

The ZIVANA Wall System is an acoustic wall system designed to absorb reverberation in the frequency ranges of speech and music, providing both the music practice room and auditorium with an appropriate Reverberation Time for their use.

What makes ZIVANA particularly suited to a school context is its durability and safety for child-frequented environments, along with a clean, orderly appearance that blends seamlessly into educational institutions without looking out of place or overly striking.

📐 The Impact of Good Acoustics on Learning — What Science Tells Us, Yet Goes Unspoken in Thai Education

Research from various institutions worldwide shows that classroom acoustic quality has a direct impact on educational achievement.

Children learning in highly reverberant rooms have up to 15-20% lower comprehension abilities than those in acoustically treated rooms. This impact is especially severe for children learning languages or musical skills, as both rely on clear and accurate hearing as a foundation.

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

✨ The Results — Sound Transformed, Rooms Transformed, Children Transformed

Following the installation of the Trandar ZIVANA Wall System in the music practice room and auditorium, the changes were immediately evident.

In the music practice room, children began to hear themselves more clearly, and teachers could provide more accurate feedback by hearing the students' actual sound authentically. Each practice session became more efficient within the same amount of time.

In the auditorium, the voices of performers and musicians reached audiences in every seat with clarity. Post-installation performances became a completely different experience for both performers and audiences alike.

"Every child has their own unique talent. Our duty is to create a space that allows that talent to shine fully — and great acoustics are the foundation of it all."
