icon_hla icon_hla_lite

"Hearing Analyzer / Hearing Analyzer Lite" is an ear wellness application that can be easily measured the frequency characteristics of your hearing. It covers a wide frequency range of up to audio band from voice band. You can self-diagnose the audio listening ability.

"Hearing Analyzer" is recommended to check your own hearing ability on a daily basis, people anxious to hearing, music players, sound professionals and all music lovers. "Hearing Analyzer Lite" is a free app that has simplified the hearing check function of "Hearing Analyzer".

By measuring the characteristics of your current hearing, please try to consider the wellness of your ears and the way of natural sound reproduction. It is possible to measure the hearing of the audio range by finding the minimum point in the operation of the slider volume that you can hear the tesing pure tone for each frequency. The results are displayed in easy-to-read charts like the audiogram.

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%.
If the volume slider is moved to the right side, the output volume will have a large gain. So as not to be excessively large gain for your ears, please adjust it carefully.
The classification of hearing ability refers to WHO.

[Procedures of Hearing Test]

Op-1 : Tap "R" or "L" button to select hearing test channel. "Hearing Analyzer Lite" is only stereo output, there is not channel selection.
Op-2 : Tap "Frequency" button to select a measurement frequency. ie. 1Khz.
Op-3 : Tap "START" button. It starts to be output the test tone, periodic sound of pure tone.
Op-4 : Move the volume slider, please looking for a limit point of listening. Increase the volume enough to slide to upper. Be careful so as not to be loud and move slowly as possible.
Op-5 : Once you have determined the minimum point of listening, please tap "PLOT" 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 : By tapping "RESET" button, you can reset the measurement result graph and each settings.
Op-9 : By tapping the "Snap" button, the measurement result graph can be saved as image data to "Photos".

[Inaudilbe Display]

The more you slide the volume slider, the louder the sound. At the maximum volume, "Inaduible!" Is displayed on the screen, and the measurement result is not reflected even if you tap "Plot" button. This state shows the hearing measurement limit level, 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 two display formats: LVL graph (broadband frequency characteristic display, no ATH correction), and ATH graph (frequency characteristic with ATH correction).

In "Hearing Analyzer", you can switch the graph display by "LVL", "ATH", "BOTH" button.

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.


LVL graph

This is a graphical representation of wideband frequency measurement.

It shows a linear frequency characteristic without ATH compensation. It covers the frequency range from 31.5Hz to 20kHz. Since the sensitivity of human hearing is different depending on the frequency band and will be a trapezoid graph in general.

Please use it if you're looking at a difference in each frequency.

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), and supports the frequency range from 125 Hz to 12 KHz.

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.
