Independent Benchmark Website DxOMark has announced a new audio benchmark that assesses the quality of a speaker's speaker system and microphones. The generated score tries to quantify the audio experience on smartphones, just like the camera performance.
DxOMark claimed to hire experienced sound engineers for a dedicated audio team that created the site's audio test protocol. An audio lab has also been set up comprising a soundproof box and a listening room for testing audio recording and speaker playback. A sonic or sonic chamber absorbs most sound waves, making the room essentially extremely quiet. To test the speaker quality, microphones are placed in the room to test the sound pressure level and output distortion of the device in the box.
The listening room tests the device by placing it in the room and reproducing audio through a series of speakers. It plays back audio samples taken by the real-world team, for example from a busy street. Other uses include selfie videos where a user holds the device in portrait orientation while two people are talking about environmental noise. Another example is live concerts to test if the device can record good quality audio.
In its first test, DxOMark evaluated seven devices, including the Apple iPhone 11 Pro Max, the iPhone XS Max, the Honor 20 Pro and the Huawei Mate 20 X, the Samsung Galaxy Note 10+, the Galaxy S10 + and the Sony Xperia 1. The final score is used to assess overall audio quality, and the scores are further subdivided to indicate playback and recording quality. From the seven devices, the Huawei Mate 20 X emerged victorious. Here are the results from DxOMark's audio benchmark.
- Huawei Mate 20 X – 75
- Apple iPhone XS Max – 74
- Apple iPhone 11 Pro Max – 71
- Samsung Galaxy Note 10+ – 66
- ] Samsung Galaxy S10 + – 65  Honor 20 Pro – 53
- Sony Xperia 1 – 45
DxOMark tests the audio experience of the device based on various parameters such as timbre, space, dynamics, volume, artifacts, and background. The website bases its evaluation on both subjective (perceptual) and objective measurements. Like the camera clippings, audio clippings will increase as audio technology and performance improve over time.
