[Ask for help] Volume is too low

Hi Guys

I am not sure if this is the right place to ask this kind of things, can anyone advice me how to play audio(mp3) file with normal volume?

I have many audio(mp3) files can play normal volume by any Players(such as QuickTime). But when I open it by Audacity, the sound
is really really too low to hear clearly. I attached Audacity menu here, may I know how to resolve this problem? many thanks.
