This analogy is extremely simplistic and incomplete: The rapid propagation of a sound wave does not impart any change in the air molecules ' drift velocity, whereas EM waves do carry the energy to propagate the actual current at a rate which is much, much higher than the electrons ' drift velocity.

To illustrate the difference: The sound and the change in the air's drift velocity ( the force of the wind gust ) cross distance at rates equaling the speeds of sound and of mechanical transmission of force ( not higher than rate of drift velocity ); while a change in an EM field and the change in current ( electrons ' drift velocity ) both propagate across distance at rates much higher than the actual drift velocity.

Over the course of hundreds and thousands of years, words may change their sound completely.

The main use of diacritical marks in the Latin alphabet is to change the sound value of the letter to which they are added.

Changing between ride and hi-hat, or between either and a leaner sound with neither, is often used to mark a change from one passage to another, for example to distinguish verse and chorus.

However, these images are still mediated by the same factors as traditional film, such as the “ moving camera, composition, editing, lighting, and all varieties of sound .” While acknowledging the value in inserting positive representations of women in film, some critics asserted that real change would only come about from reconsidering the role of film in society, often from a semiotic point of view.

He advocated restricting the amount of material to be compared ( to basic vocabulary, morphology, and known paths of sound change ) and increasing the number of languages to be compared to all the languages in a given area.

Grimm had, at last, awakened to the full conviction that all sound philology must be based on rigorous adhesion to the laws of sound change, and he never afterwards swerved from this principle, which gave to all his investigations, even in their boldest flights, that iron-bound consistency, and that force of conviction that distinguishes science from dilettanteism.

Grimm's law was the first non-trivial systematic sound change to be discovered.

Grimm's Law, also known as ' Rask's-Grimm's Rule ' is the first law in linguistics concerning a non-trivial sound change.

While incomplete and subtitled a " fragment ", its language is highly stylised with a strong emphasis on sound devices that change between the poem's original two stanzas.

Presence, released in March 1976, marked a change in the Led Zeppelin sound towards more straightforward, guitar-based jams, departing from the acoustic ballads and intricate arrangements featured on their previous albums.

Bloomfield throughout his career, but particularly during his early career, emphasized the Neogrammarian principle of regular sound change as a foundational concept in historical linguistics.

A lady, you made clear to me both by precept and example, never raised her voice or slumped in her chair, never failed in social tact ( in heaven, for instance, would not mention St. John the Baptist's head ), never pouted or withdrew or scandalized in company, never reminded others of her physical presence by unseemly sound or gesture, never indulged in public scenes or private confidences, never spoke of money save in terms of alleviating suffering, never gossiped or maligned, never stressed but always minimized the hopelessness of anything from sin to death itself.

The revolution in jazz that took place around 1949, the evolution from the `` bebop '' school of Dizzy Gillespie to the `` cool '' sound of Miles Davis and Lennie Tristano, Lee Konitz, and the whole legend of Charlie Parker, had made an impression on many academic and literary men.

Abjads differ from abugidas, another category invented by Daniels, in that in abjads, the vowel sound is implied by phonology, and where vowel marks exist for the system, such as nikkud for Hebrew and harakāt for Arabic, their use is optional and not the dominant ( or literate ) form.
