loudness

Examples of loudness in the following topics:

• Wave Amplitude and Loudness

  • Musicians call the loudness of a note its dynamic level.
  • Forte (pronounced "FOR-tay") is a loud dynamic level; piano is soft.
  • (See Dynamics for more of the terms that musicians use to talk about loudness. ) Dynamics are more of a performance issue than a music theory issue, so amplitude doesn't need much discussion here.

• Putting it All Together

  • She and the students will continue to take turns being the teacher and thinking out loud while they read.
  • The think out loud and taking turns being the teacher has proven to be very effective in helping students to focus on their learning, share their thinking about what they are learning, and bonding students into a learning community (Hashey, et al. 2003).

• Dynamics and Accents

  • Sounds, including music, can be barely audible, or loud enough to hurt your ears, or anywhere in between.
  • When they want to talk about the loudness of a sound, scientists and engineers talk about amplitude.
  • Forte means loud and piano means quiet.
  • When a composer writes a forte into a part, followed by a piano, the intent is for the music to be loud, and then suddenly quiet.
  • Here are three different ways to write the same thing: start softly (piano), gradually get louder (crescendo) until the music is loud (forte), then gradually get quieter (decrescendo or diminuendo) until it is quiet (piano) again.

• Heart Murmurs

  • Intensity refers to the loudness of the murmur, and is graded on a scale from 1 to 6, as follows:
  • 3) A loud murmur readily audible but with no palpable thrill.
  • 5) A loud murmur with a palpable thrill.
  • The murmur is so loud that it is audible with only the rim of the stethoscope touching the chest.
  • 6) A loud murmur with a palpable thrill.

• Volume

  • Speakers control the production of sound either using their own voice or a microphone so that amplified sound is loud enough to be heard.
  • Volume is the loudness of the speaker.
  • It is perceived as auditory sensation by the listener which can be ordered on a scale from quiet to loud.
  • If speaking in a face-to-face group without a microphone ask yourself if you are loud enough to be heard by audience members in the last row.
  • A sound wave with its frequency (pitch) and amplitude (loudness) labeled

• Beats

  • The loudness of the combined sound of the engines increases and decreases.
  • This varying loudness occurs because the sound waves have similar but not identical frequencies.
  • The discordant warbling of the piano and the fluctuating loudness of the jet engine noise are both due to alternately constructive and destructive interference as the two waves go in and out of phase. illustrates this phenomenon graphically.

• Explanation of Questioning

  • The internal process of being a good reader has been demonstrated to the struggling students through the out loud thinking of the teacher and their peers.

• Timbre

  • Timbre describes all of the aspects of a musical sound that do not have anything to do with the sound's pitch, loudness, or length.
  • In other words, if a flute plays a note, and then an oboe plays the same note, for the same length of time, at the same loudness, you can still easily distinguish between the two sounds, because a flute sounds different from an oboe.
  • Small differences in the balance of the frequencies - how many you can hear, their relationship to the fundamental pitch, and how loud they are compared to each other - create the many different musical colors.

• Operant Conditioning

  • In the Skinner Box experiment, there was a loud noise, which was removed when the rat pressed the lever.
  • Example stimuli may be loud noise, electric shock (rat), or a spanking (child).

• Sensory Adaptation

  • For example, if an animal hears a loud noise and experiences pain at the same time, it will startle more intensely the next time it hears a loud noise even if there is no pain.
