Yes. I've taken measurements using a decibel meter. As you'll recall, the people from the Aéroports de Montréal questioned the validity of my device. However, I've used the device for events where sound must be limited to a certain number of decibels, such as during Osheaga, in Montreal. The results provided by my device were comparable to the results provided by the city's devices. If the city's devices aren't good, then I wonder which devices are good. The level reaches 65 decibels and sometimes exceeds 80 decibels.
