I don't know if the maintainers of Freesound are around, but this file https://freesound.org/media/html_player/img/icon_background.... is loaded every couple miliseconds when the audio file plays, resulting in tens of thousands of image loads per page.
Interesting, thanks for the report. I can't see this behaviour when testing myself. Do you mean that there is a network load of the file every few milliseconds, or that the file disappears and reappears in the DOM? From what I can tell, this file is added with static CSS, so it shouldn't be reloading all the time. Are you playing from the search results page, or a sound page?
