(ii) Frequency: Number of oscillations in one second is called frequency. It controls the pitch of the sounds. High pitched sound means high frequency Hello friends! Today I am telling about the characteristics of sound class 8 in hindi.#Loudness #Pitch #Quality #CharacteristicsOfSoun What is the difference between Pitch and Loudness? • Basically, pitch is the lowness or the highness of the sound which is determined by the frequency of the noise. Loudness also affects the pitch but only as a secondary factor. • Loudness is the measure of the intensity of the sound for an observer. It is directly related to the sound intensity Loudness and Pitch. Volume or loudness of a sound depends on the amplitude. The force with which an object is made to vibrate gives the loudness. The number of oscillations per unit time. Directly proportional to frequency. Audible and inaudible sounds. Audible range = 20Hz to 20kHz known as the Sonic range. Below 20 Hz (inaudible) → infrasonic rang

Neural networks are used widely today for modeling a variety of different aspects of spoken language. We use them to model Finnish lexical prosody with an aim to shed light on the interaction between the main prosodic parameters: segmental durations, loudness and pitch. We have analyzed the performance of a group of networks which were all trained to generate values for a different prosodic. The amount of energy that is transported by a sound wave past a given area of the medium per unit of time is known as the intensity of the sound wave. Intensity is the energy/time/area; and since the energy/time ratio is equivalent to the quantity power, intensity is simply the power/area. Since the range of intensities that the human ear can detect is so large, the scale that is frequently.
