iClarified reports a comparison of the sound pressure at maximum volume from the speakers of an iPhone 16 Pro Max and an iPhone 15 Pro Max running iOS 18.
In comparison tests, it was confirmed that the sound pressure of the iPhone 16 Pro Max at maximum volume was lower than that of the iPhone 15 Pro Max, regardless of the orientation of the device.
Comparison of sound pressure at maximum volume in portrait and landscape orientations
The maximum volume comparison test for the iPhone 16 Pro Max and iPhone 15 Pro Max was conducted by comparing the sound pressure when playing the same file.
Testing was done in both portrait and landscape orientations.
Comparison test results between iPhone 16 Pro Max and iPhone 15 Pro Max
As a result, when the test file was played with the device held vertically, the sound pressure of the iPhone 15 Pro Max was recorded at 105.0 dBA, while the sound pressure of the iPhone 16 Pro Max was recorded at 103.8 dBA, which was 1.2 dBA lower.
Next, we played the test file with the device held sideways for comparison. In this test, the sound pressure of the iPhone 15 Pro Max was 91.8 dBA, while the sound pressure of the iPhone 16 Pro Max was 90.8 dBA, which is 1.0 dBA lower.
The speaker board of the iPhone 16 Pro series is larger
It has been reported that the area of the circuit board for the upper speaker of the iPhone 16 Pro series is larger than that of the iPhone 15 Pro series, but this does not seem to be proportional to the maximum volume.
