DASM – The first unit in Vietnam to own Acoustic Camera sound localization technology

As a leader in the field of acoustics, DASM has heavily invested in technology, including an Acoustic Camera system worth hundreds of millions of VND, serving noise surveys and assessments in practical projects. With this advanced equipment, DASM helps customers "see the noise", accurately identify the source, and optimize treatment options.

Acoustic Camera – A revolution in sound localization and noise identification

Unwanted noise can reduce labor productivity, pollute the acoustic environment, and negatively affect human health. However, a major challenge in acoustic treatment is accurately identifying the noise source.

This is where the Acoustic Camera becomes a breakthrough solution. This technology helps convert sound waves into visual images, allowing experts to easily detect and analyze noise sources in any space.

DASM is proud to be the first unit in Vietnam to invest in and apply the Acoustic Camera in practical noise surveys, bringing comprehensive acoustic treatment solutions to customers.

What is an Acoustic Camera?

An Acoustic Camera is a specialized device combining sound sensors and image processing technology to determine the exact coordinates of a noise source. Instead of using traditional acoustic measurement methods, this technology allows us not only to hear but also to "see" noise in real time.

How it works

The Acoustic Camera operates by:

• Capturing sound waves through a multi-directional microphone system.
• Processing signals using beamforming algorithms to identify the source.
• Converting data into dynamic thermal images, allowing users to directly observe the noise level in each area.

Practical applications of the Acoustic Camera

DASM uses modern Acoustic Camera equipment to support noise identification across various fields, from industry and construction to living and working spaces:

Noise reduction in factories and industrial zones

• Accurately identifying high-noise machinery and equipment.
• Evaluating the sound insulation performance of production areas.
• Supporting businesses in complying with regulatory noise standards.

Improving sound quality in buildings, offices, and studios

• Locating sound leakage positions.
• Evaluating sound absorption and anti-echo capabilities.
• Consulting on sound solutions suitable for architectural construction.

Supporting acoustic acceptance for construction works

• Checking the sound insulation level of HVAC systems, doors, and partitions.
• Acceptance testing of sound systems in performance centers and conference halls.
• Assessing the impact of noise on surrounding residential areas.

Checking environmental noise pollution

• Measuring noise impacts from traffic and construction works.
• Analyzing sound propagation direction.
• Proposing solutions to minimize noise impacts on the community.

Benefits of using DASM's Acoustic Camera service

Noise localization with high precision

• Determining noise source coordinates down to the centimeter.
• Detecting small sound leaks that traditional methods cannot recognize.

Visualizing noise intuitively

• Turning sound waves into dynamic images, helping investors and engineers easily understand and assess acoustic conditions.

Cost reduction & solution optimization

• Eliminating guesswork, avoiding redundant sound insulation installation.
• Saving time and costs by focusing only on treating the necessary points.

In-depth reporting & optimal consulting

• Detailed acoustic data analysis.
• Proposing smart, cost-effective sound insulation solutions.

When should you use an Acoustic Camera?

Please contact DASM if you encounter the following issues:

• The noise source in the working and living environment cannot be identified.
• Sound insulation has been implemented, but noise and echo still persist.
• It is necessary to conduct project acceptance testing according to acoustic standards.
• Want to treat noise scientifically instead of installing multiple layers of ineffective materials.

DASM is proud to be a pioneer unit in survey & noise and vibration control in Vietnam. With long-standing experience in the field of acoustics, DASM provides advanced sound measurement and treatment solutions, helping businesses and individuals control noise effectively.
