What a Techie Must Know About Sound

Can you imagine even a single day in your life without Sound? No music, no talking, and no watching movies – I think life would become pretty difficult. But, do you know the technical definition of Sound? Vibrations that travel through matter as a sound wave (a longitudinal wave) by compressions and expansions are termed as Sounds. As far as technology is concerned, there have been significant innovations in the field of sound in the form of audio devices such as speakers, radios, recording mics, vinyl records, headphones, and so much more. This article explains a few things that techies must know when it comes to Sound.

#1. Difference between Pitch and Loudness

Pitch is associated with how frequently the sound waves vibrate, whereas loudness is related to the wave’s amplitude. If the frequency is high, the pitch of the sound is high and vice versa. The high pitch of the sound refers to a sharp shrill while the low pitch is a deep sound, for instance, the sound of the horn of a ship. And as you may have guessed, loudness has to do with the volume of the sound and a high measurement of loudness usually irritates the ears.

#2. How to Take Care of Audio Devices

There are several things to keep in mind when you want your audio devices to work smoothly and last longer such as making sure the audio and video cables are not bent too tightly otherwise they might break or keeping the vents dust-free so the system doesn’t overheat. Regular maintenance for your speakers, records, and tapes can significantly improve the life span of your electronic audio devices. Professionals like to get lasting quality performance from musical equipment, so they use the best record cleaners, additional coolers, etc. Apart from all this, you must remember to place the equipment in a clean and spacious location and keep your soda can or coffee mug away from them.

#3. Why Different Instruments Make Different Sounds

Different instruments like violins, pianos, and guitars make different sounds even when played at the same amplitude and frequency. Why? Because the waves they generate are very different from each other. Instruments actually generate a lot of waves including the basic fundamental wave and other high-pitched waves (often referred to as harmonics or overtones) that combine to produce the sound we hear. Another reason is that the instruments create waves that vary with amplitudes in their own way – such as flute sounds vanish faster as opposed to piano melodies that last longer.

#4. The Proximity Effect in Microphones

The proximity effect has to do with how close the microphone is held with respect to the origin of the sound. When the microphone is kept near the source, low-frequency sounds get enhanced while high pitched sounds get boosted if the microphone is kept at a distance. Singers often use this to their advantage and get creative with the microphone. You’ll notice more of this proximity effect when you’re using a directional microphone. But remember, the microphone’s proximity effect can be a bane or a boon depending on how you use it.
