Quality data starts with quality recordings. HearAdvisor worked with GRAS to build a no-compromise front end so every test is repeatable and reliable.
Lab Assessment
MDHearing Volt Verdict
Our overall assessment weighs the MDHearing Volt's measured performance across five acoustic metrics against its position in the prescription hearing aid market. The verdict below reflects both laboratory findings and value considerations for this budget-tier device.
The MDHearing Volt is a budget-priced prescription hearing aid with excellent feedback handling but limited speech clarity performance.
- Excellent feedback handling5.0/5
- Very affordable at $397
- Rechargeable batteries for convenience
- Low speech in quiet performance1.8/5
- Poor speech in noise handling1.0/5
- No music streaming capability0.0/5
Fit Conditions
MDHearing Volt Test Summary
We evaluated the MDHearing Volt in both Initial and Tuned fit conditions to document how the device performs out of the box and after professional adjustment. Toggle between conditions below to compare the measured results.
In Initial Fit testing with a vented sleeve coupling, the MDHearing Volt achieved a normalized score of 3.1/5. Speech in quiet measured 1.8/5 and speech in noise scored 1.0/5, both below category averages. Feedback handling was excellent at 5.0/5, while own-voice comfort was mixed at 2.6/5. Music streaming scored 0.0/5, indicating this feature is essentially non-functional for quality listening.
What is HearAdvisor's Initial Fit?
The Initial Fit approximates the most likely settings and eartips for a typical moderate hearing loss. Results are measured across the same 72 acoustic scenes in our custom-built lab, then scored on a 5-star scale using an auditory model.
Metric Breakdown
MDHearing Volt Performance Scores
Our lab measures five distinct acoustic metrics for every hearing aid we test: speech understanding in quiet, speech understanding in noise, own-voice naturalness, feedback management, and streaming quality. The score card below shows how the MDHearing Volt performed in each area.
Amplification Analysis
MDHearing Volt Insertion Gain
The graph below plots the MDHearing Volt's measured insertion gain against prescriptive targets across the frequency range. This visualization reveals how closely the device's amplification matches the gain profile recommended for the test audiogram.
Audio Samples
MDHearing Volt Manikin Recordings
We captured these audio samples through an acoustic manikin fitted with the MDHearing Volt in our controlled test environment. Compare the processed output to the unaided reference recording below to hear the device's effect on speech signals.
