You can also add more target_spekers playing the same sound file. But it would be worth checking the sound file (as Obsidian-Jovani suggested). Open it in Goldwave or equivalent sound editing program of your preference and add some volume to the sound. Yet, take care you don't add too much volume and thus reduce the sound quality (all the noise will also grow stronger, and in addition it's relatively easy to get distortion).
