"...Die Ohrenärzte sind beunruhigt von der Zunahme der Gehörschäden:
Für die schädlichen Wirkungen des Lärms ist die persönliche Einstellung weitgehend belanglos. Auch wer den Lärm 'nicht hört', wem er seiner Ueberzeugung nach 'nichts ausmacht', der wird, wie sich aus Experimenten zeigt, ungünstig beeinflusst..."

Analysis of awakening reactions due to nocturnal church bell noise (Scientifc study by Mark Brink)

An event-related analysis of awakening reactions due to nocturnal church bell noise.

Probability of awakening: Scientifc study by Mark Brink (ETH Zürich)

Conclusions of the study:

It appears that the night noise situation in church bell tower vicinity is, for all intents and purposes, surely a potential object for noise regulation.

The findings of this study indicate that church bell ringing events increase the probability of additional awakening reactions that would not take place if the ringings were suspended during nighttime.

The most important predictor for awakening appears to be the maximum sound pressure level of a ringing event, thus, reducing the acoustic level of bells would be an efficient means to reduce awakenings while retaining the ringing tradition for the many that cling to it.

The maximum sound pressure level-awakening probability relationship shows a quite pronounced effect of church bells and is well comparable with similar functions from transportation noise studies that were carried out in the last years.
