Test & Measurement Services

Measure what matters. Optimize with precision.

Sound Insulation Testing

How well does your space keep unwanted sound out or in?

We assess the effectiveness of construction elements such as walls, partitions, slabs, and doors in preventing sound transmission.

Airborne Sound Insulation

Measured using STC (Sound Transmission Class) and NIC (Noise Insulation Class), this evaluates how well your partitions block airborne noise.

Impact Sound Insulation

Using IIC (Impact Insulation Class), we assess how effectively floors reduce structure-borne noise from footsteps and impacts.

Reverberation Time (RT60)

Control the echo. Enhance the clarity.

We measure how long sound lingers in a space, a critical factor in comfort and clarity. Essential for auditoriums, studios, offices, classrooms, and open-plan spaces.

Speech Transmission Index (STI) Testing

When speech clarity matters most.

STI quantifies how easily spoken words are understood in a space. This is vital for environments like classrooms, places of worship, conference rooms, and PA systems where every word counts.

Background Noise Testing

What does silence sound like?

We measure ambient sound levels to establish a baseline, helping assess acoustic comfort, check regulatory compliance, and validate design performance in sensitive spaces.

Land Traffic Noise Impact Assessment (NIA)

Protecting quiet zones from busy roads.

Required for developments near major roads or expressways, NIA evaluates how traffic noise affects residential or noise-sensitive properties.

Baseline Noise Monitoring

Pre-TOP Testing

ACMV Boundary Noise Testing

Quiet systems. Happy neighbors.

We measure noise from air-conditioning and mechanical ventilation (ACMV) systems at property boundaries to demonstrate compliance with NEA noise regulations.

Vibration & Structure-Borne Noise Testing

Mechanical systems shouldn’t shake up your environment.

We analyze how vibrations from equipment or vehicles generate sound that travels through structural elements. Crucial for industries like construction, transport, rail, and aerospace, where both comfort and performance are on the line.
