Perceiving loudness is an intricate dance between physics, psychology, and acoustics. Stringed instruments, particularly violins, violas, and cellos, add layers of complexity to this dance, given their distinctive mechanics of producing sound and the settings they are most often played in.
Thus, our sense of loudness isn't solely about the physical energy or the amplitude of the sound wave; it's a more nuanced process, influenced by an array of elements and our individual auditory traits.
When we think of string instruments, the perception of the performer and that of the audience can differ owing to their proximity to the source and the impact of the acoustics of the space. The performer, positioned close to the instrument, hears an intricate range of sounds which can seem softer. Conversely, an audience in a concert hall hears a resonant, amplified sound, which can come across as louder.
In the silent room, violinists performed on the instruments while wearing welding goggles and being surrounded by diffusive screens, reducing visual and tactile identification. Later, in the concert hall, they selected the four violins they preferred most and rated them for their projection capability.
A strong correlation emerged between the instruments favored in the silent room and those considered to project well in the concert hall. This inferred that if an instrument seems loud to the performer, it is also likely to sound loud in the concert hall, counteracting the idea that an instrument can sound gentle 'under the ear' but resonate powerfully in a concert hall.
Even though lower frequencies, with their extended wavelengths, have the potential to travel further, this doesn't necessarily correlate with an increase in perceived loudness for audience members in a concert hall. The impact of room acoustics and the frequency response of the human ear play pivotal roles in shaping this perception.
While Fritz and Curtin's study doesn't negate these influences, it offers an added layer of understanding. It suggests that the performer's perception of an instrument's loudness, even in a quiet setting, can be indicative of how the instrument will project in a larger, more echoey space.
In conclusion, deciphering the loudness in string instruments involves a sophisticated interplay of sound physics, individual auditory characteristics, instrument acoustics, and environmental factors. Research like that undertaken by Fritz and Curtin gives us a deeper understanding and appreciation of these subtleties. While the belief that an instrument can sound gentle to the player but resonate powerfully in a concert hall has been scrutinized, the exploration of loudness and projection remains a captivating field of study in acoustics and music.
This exploration into the complexities of loudness perception in string instruments such as violins, violas, and cellos serves as merely an introduction to this captivating topic. The interplay between sound physics, individual hearing characteristics, instrument acoustics, and room environment is multifaceted and extends well beyond the scope of this article. For those interested in diving deeper into the subject, you might consider further reading such as "The Physics of the Violin" by Lothar Cremer, "The Science of String Instruments" edited by Thomas D. Rossing, or "Musical Acoustics" by Donald Hall. Additionally, academic articles like those published by Dr. Claudia Fritz and Joseph Curtin can offer more specialized insights. Delving into these resources will further your understanding and appreciation of the acoustics and perception of musical instruments.
Radio City Music Hall is an entertainment venue and theater at 1260 Avenue of the Americas, within Rockefeller Center, in the Midtown Manhattan neighborhood of New York City. Nicknamed "The Showplace of the Nation", it is the headquarters for the Rockettes. Radio City Music Hall was designed by Edward Durell Stone and Donald Deskey in the Art Deco style.
Radio City Music Hall was built on a plot of land that was originally intended for a Metropolitan Opera House, although plans for the opera house were canceled in 1929. It opened on December 27, 1932, as part of the construction of Rockefeller Center. The 5,960-seat Music Hall was the larger of two venues built for Rockefeller Center's "Radio City" section, the other being Center Theatre; the "Radio City" name came to apply only to the Music Hall. It was largely successful until the 1970s, when declining patronage nearly drove the theater to bankruptcy. Radio City was designated a New York City Landmark in May 1978, and it was restored and allowed to remain open. The theater was extensively renovated in 1999.
Radio City's four-tiered auditorium was the world's largest when it opened. The theater also contains a variety of art. Although Radio City was initially intended to host stage shows, within a year of its opening it was converted into a movie palace, hosting performances in a film-and-stage-spectacle format through the 1970s, and was the site of several movie premieres. By the late 20th and early 21st centuries, it primarily hosted concerts, including by leading pop and rock musicians, and live stage shows such as the Radio City Christmas Spectacular. The Music Hall has also hosted televised events including the Grammy Awards, the Tony Awards, the Daytime Emmy Awards, the MTV Video Music Awards, and the NFL Draft, as well as university graduation ceremonies.
The construction of Rockefeller Center occurred between 1932 and 1940.[a] on land that John D. Rockefeller Jr. leased from Columbia University.[6] The Rockefeller Center site was originally supposed to be occupied by a new opera house for the Metropolitan Opera.[7] By 1928, Benjamin Wistar Morris and designer Joseph Urban were hired to come up with blueprints for the house.[8] The new building was too expensive for the opera to fund by itself, and it needed an endowment;[9] the project ultimately gained the support of John D. Rockefeller Jr.[9][10] The planned opera house was canceled in December 1929 due to various issues,[11][12][13] but Rockefeller made a deal with RCA to develop Rockefeller Center as a mass media complex with four theaters.[14][15] This was later downsized to two theaters.[16][17]
Samuel Roxy Rothafel, a successful theater operator who was renowned for his domination of the city's movie theater industry,[18] joined the center's advisory board in 1930.[19][20][21] He offered to build two theaters: a large vaudeville "International Music Hall" on the northernmost block, with more than 6,200 seats, and the smaller 3,500-seat "RKO Roxy" movie theater on the southernmost block.[20][22][23] The idea for these theaters was inspired by Roxy's failed expansion of the 5,920-seat Roxy Theatre on 50th Street, one and a half blocks away.[24][25][26] The Music Hall was to have a single admission price of $2 per person.[23] Roxy also envisioned an elevated promenade between the two theaters,[27] but this was never published in any of the official blueprints.[20]
In September 1931, a group of NBC managers and architects toured Europe to find performers and look at theater designs.[22][28][29][30][31] However, the group did not find any significant architectural details that they could use in the Radio City theaters.[32] In any case, Roxy's friend Peter Clark turned out to have much more innovative designs for the proposed theaters than the Europeans did.[33]
Roxy had a list of design requests for the Music Hall.[34][35] First, he did not want the theater to have either a large balcony over the box seating or rows of box seating facing each other, as implemented in opera houses.[36] One alternative called for "a rather deep balcony" and a shallower second balcony, but would have obstructed views from the rear orchestra.[37][38] Consequently, the final plan used three tiers of balconies, cantilevered off the back wall.[36][37] Second, Roxy specified that the stage contain a central section with three parts so the sets could be changed easily.[30] Roxy wanted red seats because he believed it would make the theater successful,[36] and he wished for the auditorium to be oval in shape because contemporary wisdom held that oval auditoriums had better acoustic qualities.[34][39] Finally, he wanted to build at least 6,201 seats in the Music Hall so it would be larger than the Roxy Theatre. There were only 5,960 audience seats, but Roxy counted exactly 6,201 seats by including elevator stools, orchestra pit seats, and dressing-room chairs.[35] Roxy also wanted the theater to have an "intimate" design as well. According to architect Henry Hofmeister, a single level of steeply raked stadium seating would likely have been used in a larger auditorium, quoting a theatrical proverb: "A house divided against the performer cannot stand."[40]
