Thank you for your interest in participating in this listening survey. The National Research Council of Canada (NRC) is carrying out a research study on how occupants of residential buildings perceive impact sounds (such as people walking, children jumping or objects being dropped onto the floor). This research will be used to help inform the potential addition of an impact sound requirement in future editions of the National Building Code of Canada (NBC).
The survey should take no longer than 25 minutes. Please take the time to carefully review each question and rate every item. Your answers are anonymous and cannot be traced back to you.

Eligibility:
  • You must be 18 years or older to participate in this listening survey. You do not need to have perfect hearing, but you should be able to hear everyday sounds.
  • This survey is open to residents of Canada and anyone living outside of Canada.
  • Your participation in this survey is entirely voluntary. The NRC will not provide any compensation for participating in this survey. You can refuse to take part in this survey now or withdraw from it at any time without penalty.
Scenario:
  • Imagine that you are sitting in your living room and you are hearing sounds from the floor above you. Rate the sounds in terms of how annoying you would find them in your daily life.
Instructions:
  • Please make sure to use headphones and to do this survey in a quiet environment.
  • Before you apply any ratings, first listen through all of the items on the 14 survey pages (there are 5 items on each page) to get used to the material.
  • Once you have listened to the material, rate the overall annoyance of each item by moving the rating slider.
  • You can listen to and switch between items as many times as you like.
  • Click «Start» below to initiate the output level calibration. Adjust your volume and audio settings until you can barely hear the test tone and then click «Start» again to begin the experiment.
  • Do not change the output volume until the experiment is finished.
  • Please remember: there are no wrong answers. Have fun!
