How to remove ".wav" from filename in find output. -name "*.wav"?

Question

bash

wrote a small script for batch transcoding files from wav to mp3

#!/bin/bash
for i in $(find . -name "*.wav");
do
  file=$i
  lame -b 16  $file $file.mp3
done

The script is run from the folder numbers
/numbers
/905xxxxxx #phone number
---/2014 #folder year
---/06 #folder month
---/22 #folder date
12_01_file.wav
12_05_file.wav
---/07
13_01_file.wav
After the script is executed, the files are converted like this 12_01_file.wav.mp3
How and where is it better to remove .wav in the script and get 12_01_file.mp3 ?
