In a test conducted by technology influencer MilesAboveTech , it was reported that audio distortion occurs when playing a video at a volume higher than 80%.

Here's a simple test, which shows that when at higher volumes the starts to have that rattle especially when audio is coming from the right. This of course only a simple clean track and not the perfect recording situation so when it comes to other content it can vary. pic.twitter.com/lRGr5G1UYA

MilesAboveTech reported the issue to Apple and received replacements twice. However, the replacement product they received did not solve the problem, and they noted that they were still having audio problems.

So I got my 2nd replacement for my iPhone 15 Pro Max from Apple and it still has the same top speaker issue?!?! When the volume is above 80% with some songs and videos the speaker rattles and cracks like it has water in it . I tried this at BestBuy too and they had the same issue pic.twitter.com/EppdilT1q9

Some users speculated that these problems may be related to the fact that the top speaker of the iPhone 15 series is extremely small. This user said, 'I think the speaker opening is too small to allow enough air to flow, so playing at a volume higher than 80% will disrupt the sound waves, resulting in audio disturbances.' .
