Hearing Analyzer Portrait 6.0

The "Hearing Analyzer Portrait" serves as a comprehensive tool for assessing auditory health by measuring hearing sensitivity across a broad spectrum of audible frequencies.

The human auditory range spans from 20Hz to 20kHz. Beyond standard audiometry (125Hz - 8kHz), this application offers extended low-frequency and high-frequency testing, including the capability to detect mosquito sounds. Users can perform self-assessments of their hearing capabilities in different frequency bands.

This tool provides insights into your current hearing profile, fostering awareness of ear health and natural sound reproduction. Hearing thresholds are determined by identifying the minimum volume level at which pure test tones at various frequencies are perceivable, with results presented in intuitive graphical formats akin to conventional audiograms.

It is recommended for audiophiles, music enthusiasts, sound professionals, and casual listeners to regularly monitor their hearing acuity. This enables users to identify potential "golden ears" and track changes over time.

Features include:

• Broadband hearing assessment across three frequency ranges: Lf (30Hz–100Hz), Std (125Hz–12kHz), Hf (13kHz–20kHz)
• Test tones at designated frequencies within each band
• Separate testing for left and right channels
• Intermittent (Tone A) and continuous (Tone B) tone options
• Result visualization through customizable graphs displaying level, ATH, or both
• Easy-to-understand settings and results with reset options
• Single-band and full-band snapshot capabilities

*1: ATH (Absolute Threshold of Hearing) is the minimum sound pressure level at which a pure tone becomes detectable in an ideal environment. While humans are capable of perceiving frequencies from 20Hz to 20kHz, sensitivity varies across this range—especially at the extremities. ATH typically peaks at mid-range frequencies (1kHz–5kHz) and requires higher sound pressure levels at lower and higher frequencies. The ATH data in the low- and high-frequency bands should be interpreted as indicative rather than definitive.

Notes include:

• The app supports Bluetooth (A2DP) headphones; wired headphones are recommended if connection issues arise.
• The test tone is generated with high gain; please exercise caution when adjusting volume.
• Before testing, set hardware volume control to approximately 50%. Adjustments upward can produce excessively loud output—please increase volume gradually.
• The hearing classification aligns with World Health Organization standards.

Remarks:

• Regular exposure to high sound pressure levels—such as listening to loud music or working amidst loud noises—poses a significant risk of hearing impairment. Users are encouraged to monitor their hearing health regularly via this app and consult medical professionals if concerns arise.
