Allion, a Promoter of Quiet Technology, Provides Various Noise-related Consulting Services
Noise negatively impacts our health and productivity. Usually, products that run silently have been more favored by users. Quietness has become a crucial evaluation point that consumers care about. Allion’s acoustic consulting team has been paying attention to related market trends for long periods. By working closely with major manufacturers, we understand the testing requirements for low-frequency background noise. For these demands, we built testing environments to modify hi-fi audio products and ensure our client’s products meet testing requirements.
Taking Care of Even the Tiniest Sounds to Become Noise-free
In an anechoic chamber, the sound waves and reflections are absorbed and only sound sources will exist in the chamber. This eliminates the influence of environmental noise and interference, providing a perfect testing environment.
The specifications of our anechoic chamber have a cutoff frequency of as low as 100Hz, a 10dBA noise floor, and a microphone measurement system configured to -2dBA. This provides an extremely accurate and low noise for measuring a wide range of frequencies.
Allion’s noise-related consulting services include:
- Noise Source Location
Pinpoint the location of the noise source. Even tiny SMD components on PCBs can be found.
- Noise Analysis
Accurately identify, classify, and quantify various noises in products.
- Sound Quality Assessment
Customized analysis equipment is used to ensure high sound quality
- Regulatory Compliance Testing
Ensuring our client’s products are by international standards and regulations. These can also be customized for our client’s specific market.
- Competitive Analysis
Help our client’s products get the best positioning in the market with noise comparisons.
Noise-related Case Study
What’s challenging about measuring noise sources on circuit boards are the small sizes of the PCB board and the low noise levels. The solutions for these two issues are often in conflict with one another.
Allion’s team has overcome this issue and developed a noise measurement testing tool to conduct positioning measurements in 4 different locations on PCB boards to locate the noise source. From the relative dB value of each point and the background noise, the location of the main noise source can be pinpointed.
From the results in the graph below, the noise source can be found in position P2.
