What is a psychoacoustic test and why?

• •Providing your reaction to sounds 

• •Web-based survey 

• •Rating annoyance to sounds 

• •Increases understanding for mitigating effects of aviation noise; may inform policy-making and aircraft design 

 

Requirements

• •Computer  

• •Stable internet connection 

• •Over ear headphones 

• •Respite from loud events prior to taking the survey 

• •Quiet room free of distractions 

Please use a personal laptop or desktop computer to access the survey through a steady internet connection.  Cell phones and tablets are not permitted.  We ask that you wear over-the-ear headphones to listen to the sounds in the test

ACTION (Hit space bar for animation once, then again)

It is preferred that you use a wired over-the-ear headphone connected directly to your computer’s microphone or headphone port

Wireless over-the-ear headphones, for example, Bluetooth headphones, may be used if an alternative wired over-the-ear headphone is unavailable.  In-ear headphones such as wired earbuds or air pods are not permitted.

ACTION (hit space bar for animation three times, third time slowly).

 Please wait at least one day to conduct the survey after experiencing loud noise events, such as attending a rock concert, mowing the yard, or extensive music playing with in-ear headphones.

Please be in a quiet room free of distractions.

What are the steps involved?

• •Introduction to the test 

• •Calibration 

• •Familiarization 

• •Practice Session 

• •Test sessions 

• • –Rate annoyance to sounds  

• •Post-test survey 

• •Technical Difficulties/Interfering Events 

 

Flowchart

 

 

This flowchart is a roadmap to the test. You are currently logged in and watching the introduction video. You will next enter your computer and headphone information.  If you do not know your computer and headphone brand name or model, you may choose not to enter this information.  You will then be taken to do a calibration of your speakers and go through a familiarization of the testing platform.  You will then watch a practice video, do a practice session, and then start the test.  You will finish up with the post-test survey. If you exit out of the test at any of those steps, you will have to go back and calibrate your speakers again to continue with the test.
