pdsounds.org offers a free sound library with a variety of interesting sound effects from a German bar to writing with an ink pen. The sound volunteers utilize recording equipment to capture hundreds of sounds for copyright free, public use and tag them with a set of tags that help in the search process. You do not need a membership to access the free sound files, and you are able to submit sounds to be added to the catalog. These sound effects are perfect for incorporation into presentations and videos. In my high school business education classroom, these sound effects will enhance our projects. For instance, if a student created a marketing video with still images of tea products, the tea pouring sound effect would be helpful. In commercials, the effects can be used to make the situation more lifelike...birds in the background of a kitchen scene, or cars in the background of a busy sidewalk. Students will enjoy searching the clip options and finding just the right combination. I give this site a 4 on a 1-5 scale, because of the variety of clips, the ability to post clips, and the ease of searching via tags and simple downloading. To improve, I would like to see thousands of sounds available for download.
