In several cases of radio reception one must measure the intensity of normal noise against a background of pulsed sequences about whose parameters there is no a priori knowledge (e.g., interference from radio communication links, internal combustion engines, etc.). The optimum measuring apparatus...

Echolocating bats adapt their emissions to succeed in noisy environments. In the present study we investigated if echolocating humans can detect a sound-reflecting surface in the presence of noise and if intensity of echolocation emissions (i.e. clicks)

Noise exhibits a richly patterned fine structure that evokes reproducible, temporally structured responses in the JONs and has been shown to reduce desynchronization in other systems25 (Supplementary Figs. 1b and 2a). We found that CAP responses exhibit transients at each switch in noise intensity:...
In this study we investigate the effects of short-term exposure to high-intensity airborne ultrasound on cognitive function. Test participants (n=40) were asked to perform a go/no-go task (GNG) and continuous performance test (CPT) under baseline (no noise) conditions. The tests were also ...
Dampening the intensity of sound waves Preventing sound waves from reflecting off hard surfaces Mitigating their resulting echoes and reverberations Balancing sound distribution throughout a spaceAs such, the right sound absorption treatments can reduce a room or building’s background noise, improve its...
The sensitivity and accuracy of the displacement measurement by this approach is directly proportional to the length of the measuring distance. Thus, laser strain meters require very deep underground installations.The precision of strain meters can reach up to one part per billion. As ...
For instance, population—the key urban element—is quite dynamic within cities, making it ‘inaccurate’ when measuring population distribution by static data like census data. As the census population only reflects a snapshot of the nighttime distribution of residents, the daytime density of the ...
In practical applications of signal detection, the roughness of a target surface significantly affects detection efficiency. In this paper, we propose a signal processing method that improves the sensitivity of a detection system by up to 100 times. In e
