The Natural Sounds and Night Skies Division supports NPS units system-wide by providing: scientific leadership to advance understanding and stewardship of natural sounds and night skies; highly specialized technical assistance; and development of policy and guidance to facilitate internal capacity building. More specifically, we provide assistance in collecting baseline data for ambient acoustic and night sky quality, identifying source specific impacts and engineered solutions to reduce, mitigate or prevent anthropogenic noise and excessive light in and around parks and national trails. We also assist with park planning, compliance, and external project reviews to help parks reduce impacts from noise and light pollution to natural and cultural resources and visitor enjoyment. The Overflights Program provides assistance related to air tour management, airspace design, military overflights, airport capacity enhancement projects, and park specific administrative flights.

During the baseline period, the participants were asked to relax in silence. At the end of the period a prerecorded female voice reminded them that the first stress test was about to begin. After the stress test, the female voice instructed the participants to relax and one of the four experimental sounds was presented. This switch between stress test and recovery was repeated three more times (see Figure 1).

where y is baseline corrected SCL, x is time (in seconds) and b1, b2 and b3 are constants. Figure 4 shows the fitted functions for the four experimental sounds. The fit, R2, for the nature sound, low noise and ambient noise was > 0.99, it was slightly lower for the high noise, R2 = 0.96. RMS-error for the nature, high noise, ambient and low noise sound was 0.0088, 0.017, 0.0090 and 0.0097 S, respectively. The half life recovery was calculated using Equation 1, by solving for x at the point where SCL had been reduced by half, compared with its value at x = 0 (see dotted line in Figure 4). The high noise had the longest half life of 159.8 s, the half life of the other three were 121.3 s for ambient noise, low noise 111.4 s and nature sound 101.3 s. Reliable statistical testing of individual half life values was not possible, since the estimated constants in several cases generated complex numbers, that resulted in missing data when half life values were calculated.

Skin conductance level (SCL) as a function of time, shown separately for the four sounds. Curves were fitted to the group data. Constants of Equation 1 and half life value (x) are indicated in each diagram.

The present results suggest that recovery from sympathetic arousal is affected by type of sound (nature sound versus noise). Recovery was faster during the nature sound (50 dBA) compared with the noises, including the low noise (50 dBA) and the ambient noise (40 dBA). The mechanisms behind the faster recovery could be related to positive emotions (pleasantness), evoked by the nature sound as suggested by previous research using non audio film stimuli [9]. Other perceptual attributes may also influence recovery. The Ambient noise was perceived as less familiar than the other sounds (Figure 2), presumably because it contained no identifiable sources. One may speculate that this lack of information might have caused an increased mental activity and thereby an increased SCL, compared with the nature sound (cf. [28]). An effect of sound pressure level can be seen in the difference between high and low noise, this difference is in line with previous psychoacoustic research [12] and is not a surprising considering the large difference (30 dBA) in sound pressure level.

Please find here the sounds for the LokSound V3.5 decoder, LokSound XL V3.5, LokSound micro V3.5, LokSound M4 V3.0 and LokSound V3.0 decoder. You also find here sounds for many locos of Brawa, Mehano, Roco, etc.

The LokSound2 decoder was introduced in 2001 and was a huge success: It was installed in many locos, e. g. Mehano or Roco. Here you find all sounds for the second generation of LokSound - also for XL V2.1.

In 1999, the LokSound "classic" decoder laid the foundations for ESU: He was not only the first LokSound decoder in due time, but also one of the first ESU products for model railway. Here you can still download appropriate sounds for your locos.

Tinnitus is commonly described as a ringing sound, but some people hear other types of sounds, such as roaring or buzzing. Tinnitus is common, with surveys estimating that 10 to 25% of adults have it. Children can also have tinnitus. For children and adults, tinnitus may improve or even go away over time, but in some cases, it worsens with time. When tinnitus lasts for three months or longer, it is considered chronic.

The symptoms of tinnitus can vary significantly from person to person. You may hear phantom sounds in one ear, in both ears, and in your head. The phantom sound may ring, buzz, roar, whistle, hum, click, hiss, or squeal. The sound may be soft or loud and may be low or high pitched. It may come and go or be present all the time. Sometimes, moving your head, neck, or eyes, or touching certain parts of your body may produce tinnitus symptoms or temporarily change the quality of the perceived sound. This is called somatosensory (pronounced so-ma-toe-SENSE-uh-ree) tinnitus.

Most cases of tinnitus are subjective, meaning that only you can hear the sounds. In rare cases, the sound pulsates rhythmically, often in time to your heartbeat. In these cases, a doctor may be able to hear the sounds with a stethoscope and, if so, it is considered to be objective tinnitus. Often, objective tinnitus has an identifiable cause and is treatable.

One leading theory is that tinnitus can occur when damage to the inner ear changes the signal carried by nerves to the parts of your brain that process sound. A way to think about this is that while tinnitus may seem to occur in your ear, the phantom sounds are instead generated by your brain, in an area called the auditory cortex.

Next, you may be referred to an otolaryngologist (commonly called an ear, nose, and throat doctor, or an ENT). The ENT will ask you to describe the tinnitus sounds and when they started, and will examine your head, neck, and ears. You might also be referred to an audiologist, who can measure your hearing and evaluate your tinnitus.

Stressed plants show altered phenotypes, including changes in color, smell, and shape. Yet, airborne sounds emitted by stressed plants have not been investigated before. Here we show that stressed plants emit airborne sounds that can be recorded from a distance and classified. We recorded ultrasonic sounds emitted by tomato and tobacco plants inside an acoustic chamber, and in a greenhouse, while monitoring the plant's physiological parameters. We developed machine learning models that succeeded in identifying the condition of the plants, including dehydration level and injury, based solely on the emitted sounds. These informative sounds may also be detectable by other organisms. This work opens avenues for understanding plants and their interactions with the environment and may have significant impact on agriculture.

What makes sounds worth of philosophical analysis is that they are notonly an important element of the perceptual scene but are alsophilosophically idiosyncratic in many intriguing ways; in particular,their temporal and spatial unfolding, as presented in perception, hasinteresting metaphysical and epistemological aspects. There is,however, an advantage of the neglect. Many philosophical aspects ofsound and sound perception are not idiosyncratic and indeed make forgeneral issues in philosophy of perception. Hence in this article wewill take advantage of the many discussions that have used othersensory features such as colors as a paradigm of a sensory feature.For instance, we shall not rehearse the discussion about thesubjectivity of secondary qualities, as the example of sounds does notseem to introduce new philosophically interesting elements that couldchallenge generalizations obtained, say, from the example ofcolors.

The main issues which are on the table concern the nature of sounds.Sounds enter the content of auditory perception. But what are they?Are sounds individuals? Are they events? Are they properties ofsounding objects? If they are events, what type of event are they?What is the relation between sounds and sounding objects? Temporal andcausal features of sounds will be important in deciding these andrelated questions. However, it turns out that a fruitful way toorganize these issues deals with the spatial properties of sounds.

The sound-as-sensations theory is justified by some facts aboutauditory experience. People report hearing voices and bells even whenno one is speaking and no bell is ringing. Various examples ofsubjective sounds are documented under the label of tinnitus. In ananechoic chamber, most subjects experience subjective buzzing andwhistlings. Some subjects undergo pathologic tinnitus when they hearsounds that disrupt their normal auditory capabilities. When Russiancomposer Shostacovich turned his head on a side, he was subject to aflow of melodies (Sacks 2008). Tinnitus and other subjective auditoryphenomena have different causes, that can be related to the mechanicalproperties of the inner ear or to more central features. The objectsof these experiences are naturally and spontaneously categorized assounds. If sounds are simply defined as the objects of audition, thenthey are easily identified with the qualitative aspects of auditoryperception. Various strands of indirect realism in perception wouldmake this view mandatory. According to them, it is by hearing theimmediate, proximal items that we hear some distal events or objects.In such a case sounds would be defined as the immediate objects ofauditory perception. ff782bc1db
