Know Personal Hearing Intelligence

Music is something we love to hear in our every mood. The bond between Music and us is much older. But the way we have heard music is changing over time. We have come a long way from radio to phones and speaker. Ever since headphones arrived, our listening habits have changed. We are so accustomed to headphones that we cannot imagine our days without headphones.

You must have noticed that after using the headphones for 10-15 minutes on loud volume, we get used to the volume and your 100% volume feels like your usual 60% volume. It happens to everyone. You know why?

There is a science behind it that science we have learnt in our 8th standard science books. When sound waves reach our ears, they cause the eardrum to vibrate. These vibrations then reach to cochlea, where they generate vibrations in the cochlear fluid. Cochlea has thousands of small hairs. These hairs are then displaced by the vibrations in the fluid. Loud sounds cause stronger vibrations, which cause the displacement of hairs more. But when you listen to this higher frequency sound for a long time, these hair cells lose their sensitivity and begin to damage. It takes time to recover and this is the time when you feel that noise level has come down. The important part is that if these vibrations are very strong, they can cause permanent damage to the hair cells.

How long & how much sound is good?

According to centers for disease control and prevention 80 db for more than 25 hours, 90 db for more than 1.5 hours, 100 db for 12 min and 110 db for more than 1.5 minute is dangerous for ears. One golden rule of thumb is the 60-60 rule. Don’t listen at more than 60% of max volume and for any longer than 60 minutes at a time.

But have you ever wondered how you can measure this noise level?

If not then here is the answer. PHI which comes with WeHear OX app is the solution of all hearing care need.

Personal hearing intelligence (PHI) is a data analytics algorithm designed to provide the best-personalized hearing assistance based on the user’s day to day hearing patterns. Its state of the art machine learning algorithms calculates your current ear age and estimated hearing loss age based on changes in hearing patterns and also provides user personalized suggestions and tips for health-friendly hearing.

PHI algorithm gives a daily PHI number between -50 to 50 based on the user’s hearing pattern data and the final PHI score is the cumulative output of the previous 7 days PHI data. The final PHI data ranges from 0 to 350 based on the hearing patterns. Higher PHI number shows more ear-health friendly hearing patterns.

How it works

Step 1. WeHear OX app runs a PHI service in background and continuously senses all the hearing patterns and stores the data for further processing.

Step 2. It analyses users hearing patterns by total minutes used with WeHear OX and other devices, Average session time, Average volume, and Average surrounding noise.

Step 3. This data runs through personalized algorithms and gives you a daily PHI score between -50 and 50 depending on your usage patterns. It calculates 7-days cumulative PHI score out of 350, which shows how healthy your hearing patterns are.

Step 4. In addition it also calculates current age of your ears and predicts possible hearing loss age based on your current hearing habits. It gives you very useful insights on hearing health and personalized tips to improve your PHI score and make your hearing habits more ear-healthy.


You get all the data with respect to minutes used with ox and other devices, average volume, average session, daily phi and average surrounding noise – in terms of graphs representation. This helps you to self-monitor your listening habits. You can also compare your PHI with others and get ranked globally and among friends.

This feature requires Wehear app service to run in background and needs user’s permission to monitor data.

Isn’t it awesome? Of course it is.

But now the question is how you can get access to PHI? It is pretty simple. PHI comes with Wehear OX app, which is available on Google play store and apple store or you can download it directly from the WeHear Website.
