    Area of Science:

    • Acoustic engineering
    • Animal audiology
    • Bioacoustics

    Background:

    • Assessing animal hearing is crucial for research and welfare.
    • Existing methods for auditory screening in animals can be complex or invasive.

    Purpose of the Study:

    • To develop and evaluate a novel hand-activated pneumatic whistle for animal hearing screening.
    • To assess the whistle's ability to produce stable acoustic bursts with adjustable frequencies.

    Main Methods:

    • A hand-activated pneumatic whistle was designed and constructed.
    • The whistle's acoustic output was characterized, focusing on burst stability.
    • Frequency adjustability was tested across a range of 6-14 kilohertz.

    Main Results:

    • The pneumatic whistle consistently produced stable acoustic bursts.
    • The device allowed for adjustable frequency selection within the 6-14 kilohertz range.
    • Preliminary use indicated the whistle's utility in screening animal hearing.

    Conclusions:

    • The hand-activated pneumatic whistle is a viable tool for animal hearing screening.
    • Its adjustable frequency and stable output make it suitable for auditory assessments in various animal species.
