Noise annoys. So, it is no surprise that people impacted by excessive aviation noise will take umbrage with insensitive tweets by aviation lobbyists. Even more so if they are suffering from sleep loss, or have asthma, blood pressure, and other health problems related to noise and aviation air pollutants.
Here is an extraordinary example: IATA.org tweeted that a plane taking off produces less noise than the vuvuzelas made famous during the 2010 FIFA World Cup in South Africa. Umm … the vuvuzela is a device INTENDED to make noise, but commercial aviation generates noise pollution as an undesirable cost of seeking air commerce profits. Yes, it is true that takeoffs are quieter than a vuvuzela, and technologies have lowered jet sound levels. But, with the way world aviation regulators are enabling excessive route concentration, the noise impacts are only intensifying.
And, for IATA.org to tweet this shows an incredible tone-deafness on their part. IATA appears to be blinded by money, and they just cannot comprehend how they are harming people and destroying residential communities.
On a practical side, the vuvuzela might help us to expose how worthless FAA’s DNL noise metric is. It would be interesting to learn, what would the DNL be if a vuvuzela was blasted for just one-second ever two minutes, for 15-hours per day? We all understand, clearly, this noise, even if made recreationally and for fun, would destroy anyone’s quality of life and lead to an early health failure. But, would those 450 daily blasts be considered impactful by FAA? Would they meet FAA’s arbitrary threshold of 65 DNL? Probably not.
Just how bad is the DNL metric? How many one-second vuvuzela blasts per day would it take to reach 65 DNL?
