Recommended: Creative description of a concert hall
The concert hall is one of man's greatest joys; enjoying a fine symphony composed by the worlds greatest, performed by a world class orchestra. For months afterwards, the borgoise attendees will speak of the energy of the conductor, the orchestra responding to him, the power of it all. The crescendoes, the diminuendos, the stark silences between movements, the clarity of the soloist above the rest of the orchestra. Little do they know that were it not for the meticulous consideration of the architect at construction time, the patrons would not feel that they were getting their money's 'worth.'
The architect is tapping into the world of acoustics; in this case, achieving the best possible sonic experience through differing techniques : different materials, certain shapes of rooms, sound traps, etcetera. Acoustics and sound, like so many physics branches, starts out relatively simple and quickly becomes a gigantic headache. Massive amounts of planning must go into a large structure such as a concert hall, a dance hall. Even small structures, such as the phonebooth, have hours of careful planning put into their design, in order to achieve the desired effect with the varied sound sources. This page is designed to inform the reader in the basics of acoustics, using the theory behind acoustics and the examples of the concert hall and the dancehall.
Technically, the definition of 'sound' is a pressure wave in an elastic medium. This means that our pressure wave can be present in air, water, wood, steel... many different solids as well as air (and liquid). One of the most common units of measurement of sound is intensity, or the rate at which sound energy is being transmitted into the medium. (low sound intensity would be something like somebody clapping between movements, high sound intensity would be the applause after Beethoven's 9th) The unit of intensity is the decibel, or db. We use a logarithmic scale to measure these, as it is difficult to understand the range of the decibel in linear terms.
Other units of measurement are the period and the amplitude of the wave. As we see in the graphic, we have the graph of time versus sound pressure, with our little wave traversing it. The amplitude is the highest value the graph reaches before descending again, while the period is the amount of time it takes for the wave to complete a full cycle.
Other terms of note for the diagram are compression, which is represented by the parts of the graph in the positive region of sound pressure, and rarefraction, which is represented by negative pressure.
The purpose of this experiment was to determine whether if the sound is affected when it travels through different length pipes. The method used to do this experiment was created by using 5 different PVC pipes in the lengths of 10, 20, 30, 40, and 50 centimeters. Then, using a tuning fork, sound will be produced on one end of the PVC pipe and measured with a decimeter on the other end. This experiment was recorded using 5 trials for each independent level and the average decibels (dB) for each pipe length were recorded.
The unit used to measure the intensity of sound is called the decibel(dB). Sounds that measure up to 75dB are considered to be in the "safe zone". Constant exposure to to sound at these levels are very unlikely to cause any lasting damage to long term hearing. The sound of regular volume conversation measures at around 60dB and the sound of a running dishwasher measures at roughly 75dB. Sounds around the 85dB level are considered a moderate risk to hearing. Exposure at these levels for extened periods of time may lead to some form of damage causing NIHL. Sounds at these levels include heavy traffic and crowded areas at 85dB, active subway stations at 95dB and listening to an mp3 player with ear buds at maximum volume at 105dB in which listening for just 15 minutes can cause permanent damage. Sound at 120dB and above are in the "danger zone". This level of sound is to be avoided at all cost as exposure even for a short pulse will lead to immediate permanent damage. This level includes the sound of ambulance sirens at 120dB, a jet taking off at 140dB and gunshots at 165 dB and above. (Rabinowitz,
The guitar origins are in Babylonia and dated back to 1850 B.C as clay plaques were dug up of people playing musical instruments which resembled the modern acoustic guitars showing distinct bodies and necks. Later evidence was found in Ancient Egypt that indicated instruments with marked frets along the neck of a primitive guitar.
...xcited to have this experience. Part of the drama of the concert at first is felt when the musicians come in and sit down and begin tuning up their instruments. I would not be able to comment on the performance of the orchestra. During the performance, I seen the audience were moving with the music, but I felt like that everyone seems knows more music than what I learned throughout this semester. After I went home and did some of the research on these music I finally understand why these people like to attend the orchestra concerto, it was because that every piece of music has a history behind it. The Los Angeles audience seemed to me to be people who know music and who will listen to something new in a respectful way. All the same, when the more familiar sounds of the last piece were heard, I could feel a little sense of relaxation and fun coming into the room.
Unless you travel into the vacuum of space, sound is all around you every day.. You hear sounds; you don't touch them. But as the vibrations that sound creates in other objects. The idea that something so intangible can lift objects can seem unbelievable, but it's a real phenomenon.
A transducer is a mechanism that changes one form of energy to another form. A toaster is a transducer that turns electricity into heat; a loudspeaker is a transducer that changes electricity into sound. Likewise, an ultrasound transducer changes electricity voltage into ultrasound waves, and vice versa. This is possible because of the principle of piezoelectricity, which states that some materials (ceramics, quartz, and others) produce a voltage when deformed by an applied pressure. Conversely, piezoelectricity also results in production of a pressure whe...
As said above, both light and sound waves have to do with interference. In sound, interference affects both the loudness and amplitude. When two waves’ crests overlap, the amplitude increases. The same is true with the troughs of the waves, which decrease the amplitude.
I attended the Los Angeles Philharmonic classical music concert at the Walt Disney Concert Hall on Friday 29 November 2013. The classical concert started at 8:00pm to the enjoyment of the huge audience that had been waiting for this amazing music extravaganza. Classical music concerts always offer magnificent entertainment and the audience in this concert was expectant to derive such entertainment or more. In attendance were Christian Zacharias who was the conductor and Martin Chalifour who was the LA Phil commanding Principal Concertmaster and Bach violin player. In readiness for the concert, I enjoyed a special dinner prepared for the audience. More specifically, LA Phil staffer introduced us to the evening classical concert amidst cheers from the audience. It was such a refreshing and joyous feeling to be part of this audience.
In order to create innovative public architecture, considered to be the most civic, costly, time intensive and physical of the arts, the project holds a degree of risk, strife, and negotiation . Overcoming these tasks and creating worthy public architecture is a challenge designers try to accomplish, but are rarely successful. The people involved in a potential public building, can be larger than the building itself. Public architecture tries to please all, even the doubters and critics, but because of the all these factors, a building is closer to failing than succeeding.

A free admission concert of classical music in the art museum. Before the concert started, going into the art museum especially in the areas where they show paintings from the Renaissance and paintings that would be considered to be from the “Aristocratic” era, had the atmosphere of a classical decade. The performance that I was seeing is a Harpsichord player named Ignacio Prego, who was playing the classical works of Johannan Sebastian Bach, which is also part of the “Goldberg Variations” where the works of Bach . When I saw him play a classical instrument, I was astonished because I have never of anything like this before, especially a classical live performance. When I was hearing the performance, the first thing that came to my head was “This is not my type of music” also when I reacted to the performance it was almost a cultural shock to me. While I kept watching and listening to the performance, I felt that I was going back in time to the Aristocratic era. Music during the time period was growing into society, although it already has before but it was a beginning for the aesthetics to learn about music and others learning to appreciate
Musical concerts are undoubtedly an incredible opportunity to experience a great aesthetic pleasure by listening to the musicians perform in front of your eyes. The power of music can hardly be overestimated – it can transfer a number of messages, thoughts and feelings through the performed sounds. Therefore the one can comprehend the music in the best possible way only when it is heard live. Musical concerts are often revelatory and highly impressive experiences to me. This essay thereby aims to provide my reflections and impressions of the concert of Gregory Porter & the Metropole Orchestra which I had the opportunity to attend in Nashville, TN.
For this task the brief was to design the construction, soundproofing and acoustic treatment of a recording studio complex within a series of set constraints. The complex had to include a control room, living room, reception and bathroom, within an overall floor space of 15m x 15m. The main focus was to be on acoustic design with the use of scale drawings to make the studio clear and easy to understand. For this studio the idea was to design a space suitable for recording large ensemble groups such as orchestras and so the space was designed with this in mind when regarding the size, shape and layout of the space. Arguably two of the most important aspects when designing a studio complex are that the live and control rooms include a lot of natural light and that the communication between the artists and the studio team is free and easy. In the studio this has achieved this by creating a design similar to and inspired by ‘The Big Room’ at Real World Studios (Realworldstudios.com, 2013), where the ‘control room’ and ‘live room’ are actually all within the one space utilising the live end/dead end theory.
Produced sound from speakers has become so common and integrated in our daily lives it is often taken for granted. Living with inventions such as televisions, phones and radios, chances are you rarely ever have days with nothing but natural sounds. Yet, few people know the physics involved in the technology that allows us to listen to music in our living room although the band is miles away. This article will investigate and explain the physics and mechanism behind loudspeakers – both electromagnetic and electrostatic.
