Sensors, to track heart rate, cadence, or to detect proximity. Microphones, to take or make phone calls, or take voice commands. Most of the "Hearables" seen to date are Bluetooth devices that use phones or PCs as the central computing unit. Vinci smart headphones, announced in 2016, [5] incorporated a dual-core CPU, local storage, Wi-Fi, and ...
In response to this, Bell Labs developed echo canceler theory in the early 1960s, which then resulted in laboratory echo cancelers in the late 1960s and commercial echo cancelers in the 1980s. An echo canceller works by generating an estimate of the echo from the talker's signal, and subtracts that estimate from the return path.
Anechoic chamber. An anechoic chamber ( an-echoic meaning "non-reflective" or "without echoes") is a room designed to stop reflections or echoes of either sound or electromagnetic waves. They are also often isolated from energy entering from their surroundings. This combination means that a person or detector exclusively hears direct sounds (no ...

[1] The visual image formed using this technique is called an echocardiogram, a cardiac echo, or simply an echo . Echocardiography is routinely used in the diagnosis ...
e. Spin echo small angle neutron scattering (SESANS) measures structures from around 20 to 2000 nm in size. The information is presented as a real-space (similar to g (r)) as opposed to a reciprocal space (q (r)) mapping. This can simplify the interpretation for some systems. [1] SESANS is useful for studying processes that occur over ...

People diagnosed with ALS live on average 2–4 years after diagnosis due to the quick progression of the disease.
