"When the nation's critical mission must go on, but the generated noise impacts the surrounding community — what is the best solution?"

 "Can noise really be reduced? From 118 dB down to 62 dB — figures that prove acoustic technology truly transforms lives."

 "Sound management is not a distant concept, but a responsibility toward everyone's quality of life."

📖 Project Story — When a national organization chooses to care beyond what is required

The 1,000-inch shooting range of the Guard Battalion, Secretariat of the Headquarters, Royal Thai Armed Forces Headquarters, is a vital training facility for national personnel readiness. Missions in this area cannot and should not stop.

However, alongside their mission, the Guard Battalion places great importance on responsibility toward the surrounding area and community.

Noise from shooting range training is unavoidable, but letting that noise disturb nearby residents is a choice. The Guard Battalion chose to address it by partnering with Trandar Acoustics to find and design the best solution for this range.

🔬 Before Solving the Problem, Understand It — The Acoustics Survey Mission

The first thing the Trandar Acoustics team did upon taking on this project was not to pitch products, but to conduct an on-site visit for systematic acoustic surveying and environmental analysis.

Because sound behaves differently in each space, building structures, construction materials, spatial dimensions, and sound propagation directions are all variables that mean off-the-shelf solutions can never yield optimal results.

The survey process that ensures accurate results

Structure and Sound Reflection Survey: The team analyzed the direction of sound reflection and propagation inside and outside the building to identify points where noise leaks into the community the most.

Sound Mapping Planning: Strategic sound level measurement points were set at 4 distances, covering both interior areas and the surrounding community radius.

Industry-Standard Equipment: Calibrated Sound Level Meters were used to ensure all recorded data is accurate and precise, serving as a reliable foundation for solution design.

Once the test signal started, baseline sound levels at each distance were recorded for the first time. The 1st distance, being the closest, measured as high as 118 dB and gradually decreased at subsequent distances. This dataset is the heart of the subsequent solution design.

   

🛠 Solutions specifically designed for this facility

Based on detailed survey data, Trandar Acoustics designed a comprehensive acoustic system that simultaneously solves both dimensions: exterior noise mitigation and interior sound quality control within the facility.

✅ Trandar Hitech Wall & Ceiling System — Walls and ceilings blocking internal noise

Hitech Wall & Ceiling System acts as the main acoustic barrier for the facility, featuring a structure designed to block high-intensity sound waves from traveling through walls and ceilings to the outside.

Choosing this system as the core solution aligns with acoustic survey data showing that most noise leaks through the building's wall and ceiling structures. Creating a strong acoustic barrier at these points is the most targeted solution.

✅ Trandar ZIVANA Wall System — Enhancing internal sound absorption performance

ZIVANA Wall System works in conjunction with Hitech Wall & Ceiling to manage echoes and reverberation within the facility.

In shooting ranges with high acoustic energy, unabsorbed sound bounces back and forth, accumulating energy. ZIVANA helps reduce this accumulation, significantly decreasing the sound energy attempting to leak outward before the main sound insulation system blocks it in the final layer.

✅ Trandar Series E — T-Bar Grid ceiling system complete in both appearance and performance

Trandar Series E is a T-Bar Grid ceiling kit that neatly and aesthetically finishes the ceiling soffit while enhancing internal sound absorption performance within the facility.

Having a complete ceiling system not only makes the space look organized but also seals gaps where sound might leak, ensuring the overall system functions comprehensively without weak points.

    

    

📊 Measurable Results — Numbers that speak louder than words

Following the installation of the comprehensive system, the Trandar team revisited the site to measure actual sound levels using the same standard equipment, ensuring a transparent and accurate comparison of results.

Average noise reduction of over 60% across all test points

These figures are not just technical statistics, but a real-world change experienced by the surrounding community in their daily lives. The previously reverberating noise that reached adjacent areas has been controlled to a safe level, eliminating further disturbance.

    

✨ The Result — A Firing Range That Meets the Needs of All Parties

Once the entire Trandar system was installed and successfully tested, this 1,000-inch shooting range became a space that perfectly fulfills requirements on both fronts.

Inside the facility, training continued with high efficiency, allowing personnel to train to their fullest potential in a better acoustically controlled environment, reducing the impact on long-term hearing health.

Outside the facility, the surrounding community regained its peace. Previously echoing noises were significantly attenuated, enabling the training ground and the residential area to coexist in harmony and sustainability.

"True responsibility is not just about completing one's mission, but ensuring that the mission does not negatively impact others. This is what the Security Battalion has proven in this project."
