Audio Equipment Speakers and Headphones Acoustic Testing Anechoic Chamber

Product Description

Product Description

The anechoic wedge is a device that reduces noise by utilizing special materials and structural design. It usually has a tapered wedge - shaped structure, and this structure enables the wedge to effectively absorb and reflect sound, thus achieving a good sound - insulation effect.

The quotations as USD 128/pc is for the size 1150*575*1200mm,of course we can also produce other sizes, please let me know your sizes.


We are not only a factory,We can provide a one-stop service from design, production, installation and delivery.

Requirement analysis: 1.Determine the purpose	Firstly, it is necessary to clarify the specific purpose of the anechoic chamber, such as acoustic metrology, equipment noise testing, etc
2.Environmental requirements:	Analyze the required environmental control conditions, including the surrounding environment, temperature and humidity, and air cleanliness, etc
Design phase  1.High performance sound insulation design:	The soundproof chamber must have extremely high sound insulation performance to effectively isolate external noise and ensure the accuracy and reliability of test data.
2.Flexibility and Scalability:	When designing, it is necessary to consider the potential increase in testing equipment and requirements in the future, ensuring that the anechoic chamber has a certain degree of flexibility and scalability.
Construction arrangement	Equipment installation: Install necessary acoustic testing equipment and environmental control systems
Testing and Calibration 1.Functional testing:	After construction is completed, a comprehensive functional test of the anechoic chamber will be conducted, including acoustic performance and environmental control effectiveness
2.Calibration equipment:	Use the free field comparison method to calibrate the sensitivity and frequency response of the microphone to ensure accurate test results

 

Specification

 

Porous sound absorption materials usually have a large number of interconnected pores. When sound waves enter these pores, the air molecules in the pores vibrate. The viscous friction between the air molecules and the pore walls plays a crucial role. Due to the interaction of the air vibration caused by sound with the pore walls, the kinetic energy of the sound wave is gradually converted into heat energy and dissipated due to this friction.

Anechoic wedge can absorb sound waves of different frequencies, maintaining a stable sound absorption effect from low frequencies to high frequencies. Moreover, it can be hung on the roof or installed on the wall according to actual needs. The installation methods are flexible and diverse, capable of adapting to different spatial layouts and building structures.

Apply For

An anechoic chamber is a special type of laboratory that is widely used in multiple fields. Its main function is to eliminate the interference of external sound waves and electromagnetic waves, providing an ideal environment for experiments. The following are the main application areas of silent rooms:

1. Acoustic testing: Silent rooms are mainly used for acoustic testing, especially in the performance evaluation of products such as audio equipment, speakers, and headphones. By conducting tests in a silent room, more accurate acoustic characteristic data can be obtained, ensuring high standards of product sound quality.

2. Electromagnetic compatibility (EMC) testing In EMC testing, a silent chamber can effectively isolate external electromagnetic interference and help engineers evaluate the performance of equipment in electromagnetic environments. This is crucial in the development and certification process of electronic devices.

3. Research and development of silent rooms provide researchers with an environment for precise measurement and experimentation, especially in the areas of sound, vibration, and electromagnetic wave research. Scientists can explore new materials and technologies here, driving the development of related fields.

4. In the development and testing of medical equipment, the silent room also plays an important role. For example, the performance evaluation of ultrasonic equipment needs to be conducted in an interference free environment to ensure the accuracy and reliability of measurement results.

5. Higher education and training institutions and research institutions often use silent rooms to teach courses related to acoustics and electromagnetics, enabling students to understand theoretical knowledge in practice and enhance learning outcomes. The application areas of the silent room demonstrate its importance in modern technological research and product development, ensuring the accuracy and reliability of experimental data.
