Depends on the frequency https://en.m.wikipedia.org/wiki/A440_(pitch_standard) https://en.m.wikipedia.org/wiki/A440_(pitch_standard)

  Did you read the article? This point is debunked right at the start (i.e. two instruments playing the same frequency still sound different).

    i think what op might be referring to is what tuning 'A' sounds like. e.g. some orchestras will tune at 415 to play older music https://www.youtube.com/watch?v=cvb7VlL_d6I https://www.youtube.com/watch?v=cvb7VlL_d6I

      Yeah, the point of the article was just that 440 hz (or 415) on one instrument isn’t the same as 440 hz from another instrument in terms of the sound.
