Though developed for NASA's use in outer space, this improved stethoscope could also be put to use here on Earth in combat situations, where ambient noise
is abundant, and in developing countries where medical care conditions are a bit more primitive.
The new Littmann model 3000 has been proven to reduce ambient noise
by an average of 75 per cent without filtering out critical body sounds, and offers amplification of up to 18 times greater than the best acoustic stethoscope.
For animals in the marine environment, there have been increasing levels of stress due to the rise in ambient noise
caused by humans.
The station lineup includes the N-8000MS Multifunctional Master Station, which is equipped with a 32-character alphanumeric LCD display, handset, and speed-dial functions; the N-8010MS Standard Master Station with keypad and handset, the N-8020MS Industrial Master Station for server environments; and the N-8011MS HandsFree Master Station offering simultaneous two-way communication via an innovative ambient noise
This calls for changing the entire facility, not just the adjustability of the work station and chair, but the lighting, visual line of sight and ambient noise
Cramlington-based Vivid Acoustics makes Soundshuttle induction loop systems, which help hearing aid users to hear more clearly by working with personal hearing aids to reduce ambient noise
and direct speech to the user.
The sound track otherwise contains just music and ambient noise
Finally, real ambient noise
was found to be suppressed by a factor 10 to 20 in the frequency range 1 to 10 mHz.
About the only drawback for this hotel is ambient noise
- a trade-off for convenience, perhaps.
the QuietCom earplug protects from high intensity ambient noise
, while permitting clear communication and improved speech intelligibility among members of Navy, Marine Corps and Air Force ground crews, a company spokesman said.
The 765HD comes with these additional standard features: computer controlled transmission; bottom tailwheel transition wear plates--replaceable abrasive resistant plate for increased boom life; personnel guard for covering the digging chain above, when crumber assembly not used; work lights--(12 volt) installed, two fore and two aft; and noise abatement--noise absorbing material at engine and deflecting panels reduce ambient noise
Another benefit is a reduction of how much ambient noise
the microphone picks up.
