31 seconds, and the lowest achievable ambient background noise
level in the space is 37dBA.
The use of ALD's improves the signal-to-noise ratio (SNR) and, as a result, speech in the presence of background noise
becomes easier to understand.
Overall, the results show a virtually complete elimination of background noise
with an accompanying improvement in voice audio quality beating all leading smartphones tested.
In the first test (audio alone), the children with ASD performed almost as well as typically developing children across all age groups and all background noise
This study seeks to determine what levels of unoccupied background noise
impact student learning by assessing the relationship between measured unoccupied background noise
levels and standardized student achievement scores from students in the surveyed classrooms.
Scientists have dubbed these persistent vibrations "Earth's hum" The largest undulations in this seismic background noise
occur at frequencies between 2 and 7 millihertz, or once every few minutes, says Barbara A.
The algorithm allows measurement of the root mean square (RMS) power for the mixture of background noise
, unvoiced fricative speech, and voiced speech encountered speech recognition experiments.
However, they are not watching TV on the PC, but rather having the TV on as background noise
while surfing the Web at the same time," says Sujata Ramnarayan, senior industry analyst for Dataquest's e-Digital Media Worldwide program.
The researchers suggest that hearing language in a setting of background noise
may even help babies learn more quickly than hearing it in isolated situations.
Designed to reduce ambient background noise
and improve audio quality, the headphones make working on a notebook computer, listening to music on a CD player or MP3 player or watching a movie more enjoyable whether traveling, in the office or at home.

The level of background noise
affects both the intensity of flavour and the perceived crunchiness of foods, researchers have found.
