    $\begingroup$ Start with the Wikipedia article Active noise control. It is how some noise cancelling headphones work. $\endgroup$ – Farcher Sep 10 '19 at 8:46

    $\begingroup$ In the "any other ways" category a vacuum blocks sounds waves, as the classic "alarm clock in a bell jar with vacuum pump" experiment demonstrates. $\endgroup$ – gandalf61 Sep 10 '19 at 9:25
