It is the psychological characteristic of physical strength (amplitude). It isperceived as auditory sensation by the listener which can be ordered on a scale from quiet to loud.Loudness is then a subjective measure of the listener, which is often confused with objective measures of
TERM TO KNOWis needed to throw the ball a long distance than is required to throw it a short one. As you speak, think of your words as balls and mentally watch thsound strength such as sound pressure level (in decibels), sound intensity, or sound power.Amplitude is the strength or power of the wave signal. Higher amplitudes on the wave graph are interpreted as ahigher volume, hence the name "amplifier" for a device that increases amplitude.LoudnessThe characteristic of a sound that is primarily a psychological correlate of physical strength (amplitude). Moreformally, it is defined as "that attribute of auditory sensation in terms of which sounds can be ordered on a scaleextending from quiet to loud."2. Using the "Naked" Speaking VoiceWhen speaking naturally without any amplification you need to keep in mind the distance to be covered byyour voice.If speaking in a face-to-face group without a microphone ask yourself if you are loud enough to be heard by audiencemembers in the last row. Speaking to a large group will require more energy to breathe and control your soundproduction.To become a better speaker with your "naked" speaking voice, try the following techniques:1.Practice speaking in a large room with a friend who moves farther and farther away from you until the friendreaches the rear of the room and can still hear you.2.Make sure that you are standing straight and not cramped so you have the maximum capacity for breathing andforcing air out of the lungs for sound production.3.Practice speaking by thinking of people at different distances to you such as at your elbow, across theroom, or in the back of a large hall.3. Using a Microphone
In large rooms or when using videoconferencing equipment, you will use a microphone to convert sound into electricalsignals for amplification.The signal may then be sent to an amplifier. The electronicamplifier increases the power of a signal. It does this bytaking energy from a power supply and controlling the output to match the input signal shape but with a largeramplitude. A loudspeaker or headset receives the input to produce the amplified sound.There are several different types of microphones that the speaker might commonly use in different situations, such as:Hand-held mics:High quality mics usually attempt to isolate the diaphragm from vibrations using foam padding,suspension, or some other method. Low quality mics tend to transfer vibrations from the casing right into thediaphragm, resulting in a terrible noise.
