Block Most SoundsNoise-cancelling headphones with intelligent noise reduction chip do block out the majority of external sounds.2. Lower Music Volumes Provides Richer Listening ExperienceMost music, however, is much richer and fuller when played at a more natural volume. Noise-cancelling headphones allow users to turn the volume down and hear the intended richness and the variations in the music that disappear when the volume is pushed to the limits.3. To Preserve Ear HealthMusic or heavy traffic generates noise levels of up to 85 decibels (dB), which sufficient to cause permanent hearing damage if we are exposed to it for several hours every day.The nice thing about noise-cancelling headphones is that much of the external sound is blocked without having to replace it with even louder sounds. 4. Noise-Canceling Headphones Are Great for TravelingFor people who often travel on commuter metro trains or airplanes, there is a great need to block out the outside noise during these times in order to sleep, read, or work. Noise-cancelling headphones allow these commuters to use their time well, even if that just means sleeping on an airplane.5. Noise-Canceling Headphones Are Ideal for StudyingMany students find it hard to concentrate, especially when sounds are distracting them at all times. Using noise-cancelling headphones helps students to block out the external world and concentrate on what they need to learn.What does Langsdom BT25PRO have?Active Noise CancellingLangsdom BT25PRO adopts the Active Noise Cancelling (ANC) tech, by using microphone to pick up low frequency noise and creating inverse waves before it reaches the ear, block out external noise before it reaches the ear, to make you immerse yourself in music.Hifi Natural Sound40mm NdFeB driver units with Titanium dome diaphragm and independent cavity, producing strong bass and wide sound stage.High consistency of the left and right driver units guarantees a well-balanced, natural sound.To Preserve Ear HealthCombine with ANC, Langsdom BT25PRO uses soft protein ear cushions which ensure long lasting comfortable wear.This means that the volume level on the music can be turned down to a more enjoyable and comfortable level and still be heard over loud noises produced by the surrounding environment. This is good news for you wishing to preserve your ear health.Great for Traveling For people who often travel on commuter metro or airplanes, there is a great need to block out the outside noise during these times in order to sleep, read, study, or work. These people-filled environments can be noisy and very distracting, especially when combined with the noise produced by the plane, metro, or bus itself. Langsdom BT25PRO allow these commuters to use their time well, even if that just means sleeping on an airplane.Ideal for StudyingMany students find it hard to concentrate, especially when sounds are distracting them at all times.

extendedDesync - A Self-Organizing MAC Protocol...
84,90 € *
ggf. zzgl. Versand

Biologically inspired self-organization methods can help to manage the access control to the shared communication medium of Wireless Sensor Networks. One lightweight approach is the primitive of desynchronization, which relies on the periodic transmission of short control messages - similar to the periodical pulses of oscillators. This primitive of desynchronization has already been successfully implemented as MAC protocol for single-hop topologies. Moreover, there are also some concepts of such a protocol for multi-hop topologies available. However, the existing implementations may handle just a certain class of multi-hop topologies or are not robust against topology dynamics. In addition to the sophisticated access control of the sensor nodes of a Wireless Sensor Network in arbitrary multi-hop topologies, the communication protocol has to be lightweight, applicable, and scalable. These characteristics are of particular interest for distributed and randomly deployed networks (e.g., by dropping nodes off an airplane).
