Loudness comparison between speech electric cello and acoustic cello

This is a sound test comparing:

• voice loudness in normal speaking

• the electric cello without amplification.
• acoustic cello

Acoustic recording is made with a A4Tech headphones mic. The sound recorded by this setup is very bad and its because of my laptop internal sound card.

Below is a Soundcloud track showing levels recorded with Audacity.
The electric cello sound is first, followed by a acoustic cello which is much louder.
