1. WHAT IS A DECIBEL?
A decibel is a measure to explain the loudness of sound. Conversation normally is around 60-65 dB.
2. WHAT IS SOUND DOSE?
Sound dose is the combination of how loud you listen and for how long you are listening at these levels. Normally if you listen to sounds that are at a high level the time you can listen for decreases rapidly. When listening to sounds at a level of 80dB, for example, an alarm clock, can be sustained for 8 hours per day.
3. WHAT DOES EXCESSIVE NOISE DO TO MY HEARING?
When you are exposed to loud noise over a long period of time, you may slowly start to lose your hearing. Because the damage from noise exposure is usually gradual, you might not notice it, or you might ignore the signs of hearing loss until they become more pronounced. This is known as Noise Induced Hearing Loss(NIHL).
4. WILL dbTrack PREVENT ME FROM GETTING HEARING LOSS?
dBTrack is meant to be used as a tool that gives the user control over their sound exposure via the smartphone device used. It is meant to warn the user when he/she has exceeded the recommended sound dose. There are many different types of hearing loss, which can be caused by many different factors, dbTrack allows the user to take charge and prevent Noise Induced Hearing Loss.
5. WHAT IS THE WHO/ITU STANDARD AND HOW IS THIS RELEVANT TO THE dbTrack APP?
You’re probably familiar with the sight of people with earbuds in their ears or draped around their necks. They cannot seem to live without their music, and are always plugged in. This might seem harmless, but they could be damaging their hearing, and may soon be facing a lifetime of hearing loss.Regular exposure to sound at high volumes and for long durations poses a serious threat to one’s hearing.
The WHO has started a campaign to raise awareness about the dangers of noise-induced hearing loss, and wants to make listening safe for everyone. They report that globally over 43 million people ages 12 -35 years live with debilitating hearing loss, and will struggle to hear their whole lives. They have partnered with ITU to bring together governments, health professionals, academia and the industry to discuss how ICTs can help make listening safe. The first of such standards have been published as ITU-T H.870 Guidelines for safe listening devices/systems
What is defined in this standard as a safe level and duration (8 hours @ 80 dB for adults, and 8 hours @ 75 dB for sensitive user i.e. children) is the backbone of what dbTrack uses to inform you what your level and duration should be based on the sound measured inside your ear.
6. HOW DOES dbTrack WORK OUT THE LISTENING TIME REMAINING INDICATED IN THE APP?
dbTrack is based on the sound exposure standard of 80 dB for 8 hours over a 40 years exposure period which will limit your risk of developing hearing loss to 3%. It further uses a 3 dB exchange rate, which means for every 3dB increase in the level being exposed to the time you can be exposed to at that level decreases by 50%. When calculating the listening time remaining, each sound sample (every 5 milliseconds) the average dB level is used and the safe listening time is adjusted accordingly. The average dB level of the recent listening session in combination with the average listening level for the day are also taken into account when calculating the safe listening time remaining.
7. WHY AND HOW OFTEN MUST I CALIBRATE?
Calibration is required when setting up the dbTrack app and whenever the app detects that a new device is being used with the earphones or when the measurements aren’t accurate anymore. The dbTrack will always prompt when calibration is required, you don’t need to worry about forgetting to do this.
8. WHAT HAPPENS WHEN A CALL COMES IN ON MY DEVICE?
You need to unplug your dbTrack certified earphones. This is because the sound sensor included in the earphone uses the microphone communication channel to update the dbTrack app on the dB level measured inside the ear.
9. CAN I USE OTHER EARPHONES WITH dbTrack?
Unfortunately not. dbTrack only works with dbTrack certified earphones that include the dbTrack patented technology to enable us to monitor sound directly in the ear canal.
10. IF dbTrack WORKS WITH A BACKGROUND SERVICE THAT SAMPLES SOUND INSIDE THE EAR, HOW MUCH BATTERY POWER DOES THIS TAKE?
The dbTrack app has been optimised to use as little battery power as possible and the battery usage is generally in line with standard music player apps.
11. CAN I INSTALL A dbTrack APP AND USE MY dbTrack EARPHONES ON MULTIPLE DEVICES?
dbTrack can currently only be installed on one device at a time. Once you install dbTrack on a new device, you will have the option to import your listening history from your old device.
12. WHAT HAPPENS IF I HAVE EXCEEDED MY MAXIMUM SOUND EXPOSURE FOR THE DAY? WILL THE APP PREVENT ME FROM LISTENING TO MUSIC?
dbTrack will prompt you to activate the auto volume levelling if not already active, to lower the volume to a level that will not damage your hearing. If auto volume levelling is active the trigger level at which auto-levelling will be lowered further to keep your hearing safe.
13. CAN I USE THE APP WHILE I AM OFFLINE?
Yes, but an internet connection is required for initial setup and data syncing.
14. CAN I TEST OTHER PEOPLE WITH THE HEARING TEST INSIDE dbTrack?
This is not advised as the hearing test result will be added to your hearing profile and the tracking of your hearing health status over time.
15. WILL dbTrack WORK ON MY DEVICE?
dbTrack works with most smartphones that have the following operating systems:
Apple: iOS 11+
*dbTrack should work on most Android 6.0 devices, if you would like to use dbTrack on an Android 6.0 device drop us an email at email@example.com with your device details (Brand, model, operating system version) and we will do our best to confirm compatibility.
