Description

Hearing Analyzer Portrait

icon_hla

"Hearing Analyzer Portrait" is an ear health check tool that allows you easily to measure the frequency characteristics of your hearing.

The human ear possesses an auditory range that up to 20000Hz. In addition to conventional audiometry (125 - 8000Hz), the extended low-frequency audiometry and high-frequency audiometry including Mosquito sounds are available. You can self-diagnose the sound listening ability.

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.

Recommended to check your own hearing ability on a daily basis for the audiophile, music players, sound professionals and all music lovers. Try to check if you have the golden ears!

The latest version has a new UI design and a continuous signal as a test tone.

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.

Operation procedures

Operation procedures in this application are as follows, please use this app carefully according to the guidelines.


[Preparation]

Step 1 : Connect headphones to your iPhone. (3.5mm jack, via Lightning connector, or wireless).
Step 2 : Set iPhone's volume to 50% by using the external button.
Step 3 : Select the type of test tone (Intermittent Tone: Tone-A or Continuous Tone: Tone-B) in the Info view. The default is the intermittent tone.
Step 4 : Tap "Close" button of the Info view.
Step 5 : Set the headphone to your ears.

[Procedures of Hearing Test]

Op-1 : Tap "Right" or "Left" button to select hearing test channel.
Op-2 : Select the frequency band (LF, BAS, MOS) and a frequency to test. ie."BAS" and "1k"".
・LF: Low frequency band (30 - 100Hz)
・BAS: Basic Frequency band (125Hz - 12kHz)
・MOS:High Frequency band (13kHz - 20kHz)

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 the "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 : By tapping "Snap/Snap-W" button, the measurement result graph can be saved as image data to "Photos".
Op-9 : By tapping "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 two display formats: LVL graph (broadband frequency characteristic display, no ATH correction), and ATH graph (frequency characteristic with ATH correction).

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 30Hz 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).

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.

Snapshot

By tapping "Snap" or "Snap-W" button, the measurement result graph can be saved as an image data to "Photos". "Snap" stores the measurement result graph for the currently displayed single frequency band, while "Snap-W" stores the measurement result graph for the entire frequency band. Since it can save with time stamp, please use it when you want to save your measurement result.
