I will use android studio program to create android application. The language will be java, and the application I want to make will be a noise canceling application that eliminates the noise heard in a running car. To do that, you need to have the following function:
1. Real-time noise measurement function coming from the mobile phone microphone
2. Function to grasp the frequency of the measured noise
3. Continuously monitor noise levels and adjust algorithm
4. Continuously learn and adapt to new noise patterns
3. Reverse claudication frequency generation function
4. User-friendly UI provision function.

IMPORTANT: I need to ensure that I am not interfering with important sounds such as emergency vehicle sirens or car horns.

To do this, the following techniques will be used:
1. Fast Fourier Transform (FFT) technology
2. Active Noise Cancellation (ANC) technology
3. Android SDK
4. Etc. The words with all capital letters should appear at least 4 times.
