Soundproof for Sound Measurement

AEB

When we think of “Soundproof,” we often imagine soundproof rooms or studios for playing musical instruments in residential settings. However, Sonora Technology specializes in soundproofing not for general purposes, but for the measurement of product acoustics used by automotive manufacturers and home appliance companies. They produce soundproof test chambers, anechoic chambers, and other such equipment specifically designed for measuring sound.

In other words, instead of soundproofing for musical purposes, what is required is soundproofing for the purpose of measuring sound.

Example:
A home appliance manufacturer, Company A, frequently received complaints from users about the loud wind noise of their desktop fans. To address this issue, the company decided to develop a quieter desktop fan. To achieve this, they needed to measure the noise levels of both the prototypes and the existing models.

To measure noise levels, a noise meter and a quiet environment for measurement are required. However, the development team was unsure about the specific type of noise meter or environment needed and consulted Sonora Technology. As a result, they set up the following equipment and environment:

• Measurement Device: Sound level meter (with frequency analyzer)
• Measurement Environment: Anechoic box (designed to ensure measurement distance)

In this setup, a microphone (sound receiver) is placed at a fixed distance from the desktop fan (sound source) to measure the sound emitted by the fan. The acoustic data measured by the noise meter is displayed in terms of sound pressure levels across various frequencies.

Thus, measurement equipment and environments can be tailored to the specific conditions of the items being measured. Naturally, the size of the required room or box changes depending on the size of the object being measured. To measure sound effectively, it is essential to create a quiet environment. Measurement cannot be accurately performed in a noisy environment. Therefore, soundproofing technology is necessary.
