What’s Effective Communication

Published by:

Effective communication is a somewhat esoteric concept that is frequently applied to business management. It can, however, easily apply to our personal lives as well.

Put simply, effective communication aims at improving our understanding of the emotional content (*taps head and does a bad Bruce Lee impersonation) behind any given information. Theoretically, this understanding makes us more empathic and thus better able to relate to our spouses, co-workers, employers and friends.

effective communicationsEffective communication, then, aims at fostering a deeper understanding between communicators, by creating a stronger emotional resonance.

Experts in the subject maintain that the first step towards becoming a more effective communicator (should you wish to, of course) is to become a better listener. You can do this by fully focusing on the speaker (as opposed to being distracted, or deliberately distracting yourself), not interrupting them and openly demonstrating an interest in what the speaker has to say.

The next step, maintains that the use of open body language (e.g. not crossing your arms) and emphasizing a point via your body (such as tapping your head to indicate thinking ahead) is also very important to effective communication.

Step three is to focus on and thus better manage, your stress. A stressed person, even if their outward demeanour seems pleasant enough, gives off a lot of anxiety, from body language to posture, so it is best to deal with your anxieties privately before dealing with others (where possible).

Of course, effective communication is largely emotion-centric as a concept and so the final point brought up by the article is to improve your own emotional awareness. Essentially, this is the understanding of yourself and what makes you tick. It sounds obvious, even easy, but the truth is that most of us don’t have a clue. If you find yourself entrenched in petty squabbles or constant bickering with your friends, spouse, family or colleagues, then there is a good chance that there is something deeper that is bothering you. With a greater emotional understanding of yourself, not only will you be able to avoid potentially stress-inducing situations, but you should also be able to recognize patterns in others that you have seen in yourself, allowing you to become more empathic and, ultimately, a better communicator.

Essentially, effective communication is all about communicating effectively. It is about improving your understanding of yourself and others around you, in order to live and work with other in a more harmonious way.

What Is an Ultrasonic Transducer?

Published by:

Without giving too much about this earpiece article, but I found it remarkable and relevant to what I’m currently doing.

An ultrasonic transducer is an electrical component that converts ultrasonic sound waves beyond the range of human hearing into alternating current (AC) or direct current (DC) electrical signals that are then transmitted or recorded. Usually such devices are built upon crystals that demonstrate a piezoelectric effect, which conduct electrical current in response to mechanical stress or vibrations. The crystals have directly proportional output to the strength of the input sound wave or stress, and this makes them useful measuring devices as an ultrasonic transducer.

ultrasonic transducerApplications for ultrasonic transducer-based electronics included use in early television remote controls as signal devices, and, as of 2011, in anemometers used by weather stations to monitor wind course and speed. They are used in industrial applications to monitor the level of fluid in a tank, and in modern-day automobiles as of 2011 for echo location sensors to indicate objects in close proximity to the path of a vehicle that is backing up or pulling into a garage. Since an ultrasonic transducer can also play the role of an ultrasonic transmitterthrough input electrical power, they offer the capability of a primitive type of sonar in many cases. Sound waves can be reflected off of a surface and the distance to that surface measured by the time and frequency of the wave that bounces back.

Electrical devices that convert one form of energy to another, like ultrasonic sensors, often have widespread applications in electronics and industry. Many diverse uses for the ultrasonic transducer now exist, including in environmental controls for buildings, such as in humidifiers where they vaporize the surface of the water, and in burglar alarms to detect objects moving within an otherwise clear path. Ultrasonography also relies on the principle of an ultrasonic transducer in medicine, where sound waves of 1 to 30 megahertz are employed to remotely generate imagery for the state of muscles, internal organs, and blood vessels in the human body, as well as the state of a fetus during pregnancy.

Since the era of the 1940s, the ultrasonic transducer has been incorporated into testing equipment to detect flaws in a range of sonar-related applications. They can be used to find fine cracks, voids, or porous sections in concrete and building foundations, damaged or fractured metal welds, and flaws in other materials such as plastic, ceramic, and composites. The devices are versatile because the sound waves that they emit will be affected by any medium, whether liquid, solid, or gas. With a detector used to measure gas status, however, an intermediate gel is usually placed between the gas and the ultrasonic transducer, as sound waves are otherwise poorly conducted and recorded in a gas medium.

The field of flaw detection for ultrasonic technology is broken down into five different types of transducer designs: contact, angle beam, delay line, immersion, and dual element transducers. Contact transducers have to have close contact proximity to what they are measuring, such as a stud finder in the building trade used to detect wooden beams behind walls. An immersion transducer is waterproof and placed in a fluid flow. Both angle beam and delay line forms of an ultrasonic transducer are used to measure welds and in conditions of high temperatures. The dual element transducer is simultaneously a transmitter and receiver for continuous monitoring of rough or potentially flawed surfaces.
