Petralex Mobile App

Turn your smartphone into a fully functional hearing enhancement device!

Petralex is a revolutionary yet practical application for smartphones and tablets with all the functions of a hearing aid, but the app is not intended to substitute professional testing and professionally fitted commercial hearing aids. With Petralex you can use your mobile device with a pair of regular headsets (including Bluetooth), as a simple yet discreet hearing enhancement device, without the need for a battery that needs changing or the need for a special hearing device.

The processing power of modern smartphones is so high that you can conduct a hearing test and enhance your hearing easily in a matter of minutes. Any smartphone has a built-in microphone and a headphone (or headset) jack, which can be used as a base for an advanced digital hearing aid. The Petralex app walks you through initial testing to see if you need hearing enhancement. Thereafter the app is able to automatically enhances hearing by the amounts detected. In keeping with its philosophy of making digital services inclusive and affordable for all Sri Lankans, Dialog has negotiated a special discounted monthly subscription fee of Rs.180 +taxes compared to the global monthly rate of Rs.2000 +taxes.”
