Aviation noise, especially in a densely populated country like The Netherlands, has become a serious problem for many citizens over the past 5 decades or so. On 21 February 2021, the National Institute for Public Health and the Environment has published a new report in which it says that more and more people are suffering from aviation noise, even though there’s no significant increase of the amount of dBs. The Institute concludes that their current research methodology might fall short as they cannot take into account “non-acoustic factors.” Well, besides those important non-acoustic factors, other acoustic factors besides dBs can also be relevant to take into account. See my reactions on the report in the Dutch daily Algemeen Dagblad and the news site of RTL Nieuws.
