SUPPLEMENTARY INFORMATION:

I. Abstract


[top] This information collection is for conducting a sound response laboratory test, which is called a psychoacoustic test, to better understand human noise response to passenger and equivalent cargo carrying Advanced Air Mobility page 16889 (AAM) aircraft. These AAM aircraft are expected to takeoff and land in closer proximity to communities than conventional aircraft. The aircraft are being designed to use multiple electrically driven rotors. Different AAM aircraft are unique in their design and geometric placement of rotors around the aircraft. The unique propulsion systems of AAM aircraft means that the sounds they produce will also be unique compared to conventional aircraft. Yet, insufficient data exists on how humans will respond to AAM aircraft noise. The National Aeronautics and Space Administration (NASA) seeks to gather data on the human noise response to AAM aircraft through the Varied AAM Noise and Geographic Area Response Difference (VANGARD) laboratory test. The VANGARD test will play recorded and electroacoustically reproduced sounds of different single AAM aircraft flyovers to test participants and ask for their annoyance response to each sound. The VANGARD test is one of many initial psychoacoustic tests being planned to gather data for research purposes on AAM vehicle noise response. VANGARD test objectives are not designed to affect existing or proposed aircraft operations, and its objectives are not designed to affect noise policy. One aspect of the VANGARD test that is different from many other psychoacoustic tests on AAM vehicle noise is that it will be conducted using an online test application and gather human response data from geographically diverse participants. By addressing insufficient data on AAM aircraft noise response, VANGARD test results will allow subsequent studies on human noise response to AAM aircraft to be more informed in their design and test objectives. The VANGARD test seeks to answer the following research questions that will serve as a foundation for further investigations with laboratory and community testing of AAM/UAM noise human response:

1. Do annoyance responses differ between respondents who reside in low versus high ambient noise environments? Here, "low" and "high" ambient environments are determined from the A-weighted L50 data produced by the National Park Service for different United States Postal ZIP Codes.

2. Do annoyance responses differ as a function of the phase of flight? Here, the phases of flight are the landing, takeoff, and cruise phases.

3. Do annoyance responses differ as a function of distance from take-off and landing operations?

4. Is there a correlation between annoyance ratings and objective parameter analyses of the data? Examples of objective parameters include, but are not limited to, sound quality metrics, spectra, sound exposure level, and amplitude envelope shaping.

5. Is there a correlation between annoyance ratings and noise sensitivity, measured from subject questionnaire data?

Authority: The National Aeronautics and Space Administration (NASA) is committed to effectively performing the Agency's communication function in accordance with the Space Act section 203 (a)(3) to "provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof," and to enhance public understanding of, and participation in, the nation's aeronautical and space program in accordance with the NASA Strategic Plan.

Through Public Law 93-579 (Privacy Act of 1974), the authority to collect the information requested from test participants through informed consent associated with the study is derived from one or more of the following: title 14, Code of Federal Regulations, §§?1212 and 1230; title 51, United States Code, section 20113, as amended.

The VANGARD test was approved by the NASA Institutional Review Board with Study eIRB Number STUDY00000862 and FWA Number 00019876.

II. Methods of Collection

Test subjects will electronically indicate their annoyance rating to test AAM/UAM aircraft noise stimuli into an interface displayed on their own computers.
