The sense of pitch depends on the intensity of the tone, as shown in the graph; below 1000 Hz, pitch tends to drop with increasing loudness, and above 1000 Hz, tends to rise. A tone must have a certain duration for pitch to be ascribed; if not, it is heard as a CLICK.

The sensation of a frequency is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.

1 Answer. (i) The loudness of a note is determined by its amplitude. (ii) The pitch of a note determined by its frequency. (iii) The quality of a note is determined by its wave form.

Characteristics of Musical Sound

• Pitch: The pitch is the characteristics of a musical sound which depends upon the frequency.
• Loudness: The loudness of musical sound is related to the intensity of the sound the higher is the intensity, the higher will be the loudness.
• Quality or timber:

• duration. -speed of the tempo.

Musicians point to three distinguishing characteristics of musical notes: loudness, pitch, and timbre (or “quality”).

The loudness of sound is determined, in turn, by the intensity of the sound waves. Intensity is a measure of the amount of energy in sound waves. The unit of intensity is the decibel (dB).

Wavelength is not a characteristic of musical sound. Pitch, Quality and Loudness are all characteristics of a musical sound.

Musical sound, any tone with characteristics such as controlled pitch and timbre. The sounds are produced by instruments in which the periodic vibrations can be controlled by the performer.

The two main properties of sound are frequency and amplitude. The frequency of the sound waves determines the pitch of the sound. The amplitude of sound determines the loudness. The quality of sound is affected by the pitch and the loudness.

Amplitude is the size of the vibration, and this determines how loud the sound is. We have already seen that larger vibrations make a louder sound. It is only useful or meaningful for musical sounds, where there is a strongly regular waveform. Frequency is measured as the number of wave cycles that occur in one second.

The wavelength of a sound is the distance between adjacent identical parts of a wave—for example, between adjacent compressions as illustrated in Figure 17.8. The frequency is the same as that of the source and is the number of waves that pass a point per unit time.

For example, a small bell. If an object vibrates slow, it makes a low pitch sound. For example, a large drum.

Something that sounds deep and soft, especially someone’s voice, can be called low-pitched. People who sing in low registers — altos and basses, for example — have low-pitched voices, and a big dog might have a low-pitched bark, especially compared to your toy poodle’s yap.

Higher pitched sounds produce waves which are closer together than for lower pitched sounds. Another factor which produces higher pitched notes is the tension within the vibrating object. A guitar string can be tuned to a higher pitch by adjusting the string tensioner.

High pitch:

• Nails scratching on blackboard.
• School bell.
• Whistle.
• Rubber shoes squeaking against a basketball court.
• Fireworks.

1. You hear a high-pitched squeal when accelerating: If you notice a loud squeal when accelerating, especially if your car is just warming up, it could be that you have a loose or worn fan belt. Usually if your fan belts are worn, it could mean your timing belt needs replaced as well.

Tinnitus happens when we consciously hear a sound that does not come from any source outside the body. It is not a disease, but a symptom of an underlying problem. The noise is usually subjective, meaning that only the person who has tinnitus can hear it. The most common form is a steady, high-pitched ringing.

Anxiety activates the fight or flight system, which puts a lot of pressure on nerves, and increases blood flow, body heat, and more. This pressure and stress are very likely to travel up into your inner ear and lead to the tinnitus experience.

The brain creates noise to fill the silence, and we hear this as tinnitus. Perhaps only someone with profound deafness can achieve this level of silence, so paradoxically loud. I have it easy, and in fact kind of like my tinnitus: it changes pitch from time to time, an ethereal deep outer space keening.

Our stress levels go up with less sleep or if you are suffering from long-term sleep difficulties. And, when stress levels go up tinnitus can seem louder. If you have not slept properly one night you might experience higher stress levels, and your tinnitus might seem louder than on a normal day.

Studies have shown that turmeric extracts have a positive anti-inflammatory response in ear conditions. In addition to this, treatment with turmeric for middle ear infections – which commonly cause tinnitus symptoms – was found to be as effective as antibiotics.

Suspected superior semicircular canal dehiscence is diagnosed with non-contrast temporal bone CT scan and increased intracranial hypertension is worked up/treated by Neurologists. New sensorineural hearing loss and non-pulsatile tinnitus diagnosed within 30 days of onset may be treated with oral or injectable steroids.
