When it comes to headphones, there are lots of things buyers want to understand. Most often, they want to understand because they desire to make the right decision in terms of what will represent a good value for their investment. They want to be certain that the headphone will transmit the quality of sound they desire. In such circumstances, specifications such as drivers, impedance, sensitivity, total harmonic distortion, noise attenuation, sound pressure level and others will matter so much.
In addition to these, buyers may also need to pay close attention to such parameters as frequency, amplitude, and wavelength. While these parameters play an essential role in the way we hear sounds from the headphone, they are also important in determining the safety of the headphone. We will briefly consider these parameters to give you an idea of what to expect and how to use your headphone.
The Science of Sound
The sound we hear travel in forms of waves. The ear enables you to hear because it has the capacity to convert the vibrations of sound waves to signals that the brain will understand. How the waves are converted also depends on the wavelength, the frequency, and the amplitude.
In physics, the wavelength is the distance between two adjacent crests or troughs. It is measured in meters. Wavelength is considered more seriously in engineering fields that work with sound and you may not know how important it is when you are enjoying your headphone. But it interacts with frequency to determine sound pitch.
The frequency of a sound wave is the number of vibration cycles per second and is measured in Hertz (Hz). The frequency of a sound wave is the major determinant of the pitch, and this is very important in how your ears hear sounds. The human ear can detect a wide range of frequency (between 20Hz to 20,000Hz).
In physics, the amplitude is the maximum disturbance of the medium (air in sound) from its equilibrium. It describes the strength of the sound wave. It relates directly to the volume of the sound you hear and not with the frequency. Music basically consists of a mixture of different frequencies and amplitudes.
Moving away from the science of sound, pitch and volume are basically human perceptions. They combine with other factors to influence the way we hear the music. Headphone makers always ensure that their products cover as wide a spectrum as possible so that the products produce the right sound. It is also important that you listen responsibly as excessive sound pressure can damage the ear. Knowing that the volume depends on the amplitude of sound waves you need to keep it in check to avoid exposing your ear to damage. Also, limit the time you expose your ear to loud sound.
