Both studies demonstrate that passive acoustic recording is a reliable method to assess relationships to acoustic communities over space and time.īackground. Results from this study indicate that prescribed burning does alter the soundscape, especially early in the post-burn period, but the effects are ameliorated by a significant increase in biophony as the growing and breeding season progressed into the warmer summer months. In addition to examining acoustic changes over time, I examined differences between 11 burned and unburned pastures. Using the same suite of acoustic indices from Chapter 1, in Chapter 2 I examined acoustic recordings at a much larger time scale to determine distinctive acoustic events driven by biophony and geophony across a 23-week period. Finally, I show that favorable habitat for a critically endangered necrophilous insect, the American burying beetle (Nicrophorus americanus) can be identified by the acoustic signature extracted from a short temporal window of its grassland ecosystem soundscape. Although reproduction of all species examined is dependent upon securing small carrion for reproduction, I found that known habitat and activity segregation of five Nicrophorus beetle species may be reflective of the soundscape. tomentosus was consistently positively correlated to places with higher levels of biophony. marginatus was consistently negatively correlated to higher levels of biophony, while N. In addition to positive associations with the soundscape, we found that N. americanus trap rates showed a positive correlation to areas of increased acoustic complexity specifically at dawn. In Chapter 1, I found that associations between Nicrophorus burying beetles and the soundscape were unique to particular species, acoustic indices and times of day. Acoustic index values were used to determine the relationship between Nicrophorus burying beetle species composition and the prairie soundscape (Chapter 1) and to determine if prescribed burning changes the composition of the soundscape over time (Chapter 2). Both studies were conducted at the Nature Conservancy’s Tallgrass Prairie Preserve (36★0’N, 96☂5’W) and used six acoustic indices to quantify the ratio of technophony to biophony, acoustic complexity, diversity, evenness, entropy, and biological acoustic diversity from over 70,000 sound recordings. ![]() Two studies were carried out by employing ecoacoustic methodology to study grassland carrion food webs and to capture the phenology of a grassland soundscape following a prescribed burn. Ecoacoustics, the study of environmental sounds using passive acoustics as a non-invasive tool for investigating ecological complexity, allows for long-term data to be captured without disrupting biological communities. However, the Sound Remover effect looks to be a miracle worker in those regards, as it can literally identify and obliterate complex sounds from your mix without completely destroying the audio you want to keep.Tallgrass prairies are rapidly vanishing biodiversity hotspots for native and endemic species, yet little is known regarding how spatial and temporal variation of prairie soundscapes relates to seasonal changes, disturbance patterns and biological communities. When this happens, it has the potential to make your post production sound process a complete nightmare. will inevitably make their way into your sound mix, oftentimes unknowingly. ![]() Where tools such as the Sound Remover effect will really come in handy is when you're dealing with footage that was shot on location (as opposed to on a soundstage.) When you don't have complete control over the sounds at your location, various wild sounds such as traffic, airplanes, refrigerators, lawnmowers, dogs, etc. Ready to have your mind blown? Check out the video to see this new effect in action: Here's a quick tutorial courtesy of the fine folks over at Infinite Skills that sheds light on how easy it is to fix all kinds of audio problems with the new Sound Remover effect. Now with Adobe's latest offering in the audio production field, Audition CC, fixing problematic audio should be as simple a process as ever. The ability to seamlessly roundtrip audio clips between Premiere and Audition made the choice all that much easier. One of my favorite tools for the past year has been Adobe's revamped version of Audition. Luckily for us, high-end tools have never been easier to use or more affordable. Audio post-production can be a major pain for those of us who don't have (can't afford) a proper audio post team. ![]()
