<br>like, it sounds exactly the same loudness whatever the volume, so long as it's not 0 (my headphones are sitting beside the laptop - they're going nowhere near my head)<br><br><div class="gmail_quote">On Tue, Aug 23, 2011 at 10:05 PM, Jonathan Wilkes <span dir="ltr"><<a href="mailto:jancsika@yahoo.com">jancsika@yahoo.com</a>></span> wrote:<br>

I've managed to hurt my ears twice over the past two days when using PD w/ headphones. Even at lowest system volumes, it seems that Terrible Things can happen. Are there any precautions that I can take to make it feel less like I'm taking my life into my hands when I have to use headphones?<br>
