How to evaluate the performance of Bluetooth speaker
In addition to the regular evaluation of the wireless Bluetooth speaker, the more important thing for consumers is the performance of the wireless Bluetooth speaker. This part of the test is mainly judged by detailed scores. The test items are also various, and each link is closely related to the user's daily experience. How to evaluate the performance of Bluetooth speaker?
First, compatibility evaluation. We will select the mainstream front-end platforms: PC, Android, IOS, Windows Phone 7 to pair test each mobile Bluetooth audio, first to see whether it is successful, and then to see the complex process of pairing. See the number of mobile Bluetooth audio functions. Bluetooth speaker manufacturer
Second, transmission distance test. We will simulate physical barrier and no physical barrier for testing. Physical barrier is mainly door and wall, and we will compare the wireless transmission capacity of each product.
Third, anti-interference ability test. Simulate the user's actual use environment, and test whether the wireless signal can be successfully connected in a complex situation, such as router, other 2.4G devices and Bluetooth devices. Shenzhen Bluetooth speaker manufacturer
Fourth, endurance test. First of all, we will find a decibel of the commonly used volume so that the volume level of each product participating in the evaluation can reach a unified decibel for continuous continuous endurance test to test its real endurance time.
Fifth, subjective listening test (call quality and music playing quality). Due to the special function of mobile Bluetooth audio, we will measure it according to the standard of conventional audio quality, and consider the distortion, resolution, low frequency and other aspects to obtain the real audio quality score. In addition, we will also compare the call quality of Bluetooth audio.
