Hearing Analyzer Lite


"Hearing Analyzer Lite" is a hearing health app to easily check the frequency response of your hearing.

It covers a standard audible frequency range from 125 Hz to 12000 Hz. You can self-diagnose the sound hearing ability.

In general, a high risk of hearing loss has been known if you continue to hear the sounds of a high acoustic pressure level, such as listening of the portable audio and working with too loud noises.

This app allows you to check your hearing characteristics by finding the gain point of smallest audible tone for each frequency. The results are displayed in easy-to-read charts like the audiogram. Please try to consider the wellness of your ears and and your natural hearing by knowing your current hearing status.

In the latest version, we have updated the UI design and changed the hearing test method to the same as the paid iOS app "Hearing Analyzer Portrait".

In general, a high risk of hearing loss has been known if you continue to hear the sounds of a high acoustic pressure level, such as, listening of the portable audio and working with too loud noises. According to WHO, some 1.1 billion teenagers and young adults are at risk of hearing loss due to the unsafe use of personal audio devices, including smartphones, and exposure to damaging levels of sound at noisy entertainment venues such as nightclubs, bars and sporting events.

# Attention:

Please use the earphones that provided with the iPhone in the hearing test.
This application generates a test tone signal with a high gain, so please special attention to the volume adjustment.
Before the diagnosis start, please set the hardware volume control to the central position of 50%.
Carefully adjust the playback volume so as not to be excessively large gain for your ears.
The classification of hearing ability refers to WHO.

Step 3 : Select the type of test tone (Intermittent Tone: Tone-A or Continuous Tone: Tone-B). The default is the intermittent tone.
Step 3 : Tap "Close" button of the Info view.
Step 4 : Set the headphone to your ears.


[Procedures of Hearing Test]

Op-1 : Tap "Left" or "Right" button to select hearing test channel. "Hearing Analyzer Lite" is only stereo output.
Op-2 : Select a frequency to test. ie. 1k.
Op-3 : Tap "START" button. It starts to be output the test tone, periodic sound of pure tone.
Op-4 : Adjust the software volume to find the minimum sound point at the limit of audibility. Be careful so as not to be loud and move slowly as possible.
Op-5 : Once the minimum point of hearing is determined, tap "Stop" button.
Op-6 : Subsequently, if you want to measure the frequency of the other, please repeat from the operation of Op-1.
Op-7 : Please tap "Graph" button after these measurements were completed. Result of the measurement graph is displayed.
Op-8 : If you tap "Reset" button, you can reset the measurement result graph and each settings.

[Inaudilbe Display]

At the maximum gain of volume control, "Inaduible!" is displayed on the screen, and the measurement result is not reflected even if you tap "Plot/Stop" button. This state shows the hearing measurement limit level.In "Hearing Analyzer Portrait", the frequency button turns yellow and a warning is displayed.

Testing Result Graph

This app will display a graph result of the measurement of the minimum sound in each frequency that you could take to hear. The measurement result graph has a ATH graph (frequency characteristic with ATH correction).

In addition, you can switch channels in the graph display with x (Left), o (Right), and xo (Left and Right) buttons.

Please use them to compare measurement results as necessary.

ATH Graph

This is a graphical representation applied compensation of the frequency characteristics to fit the lowest audible value of human beings. If it is a higher level and flat as possible, the graph is estimated to be good condition of your hearing.

This graph has the same characteristic display as the general hearing test (Audiogram).

In addition, the Absolute Threshold of Hearing (ATH) is the minimum sound pressure level that can be detected by hearing noise-free environment. It has been corrected to be a flatter graphical representation for each frequency in the case of normal hearing. However, it may display levels vary significantly, due to the surrounding environment and individual differences. On LF and MOS frequency band, the information in ATH graph is just for reference purposes.
