Historically, operas weren’t carried out with microphones, however nowadays many performances happen in giant theatres which have been constructed for a a number of array of musical productions, largely electrified music sorts, not an acoustic artwork like opera. “One of many most important causes for using microphones in opera productions is to make sure that the viewers can hear the performers clearly, particularly within the case of the Salle Wilfrid-Pelletier (SWP),” defined Patrick Belzile, technical director at Opéra de Montréal throughout the creation of The great thing about the world.
SWP seats 2,982 folks, making it one of many largest halls for opera. To get a perspective, here’s a comparative checklist with some measurements of essentially the most well-known opera homes on the earth (from Live performance Halls and Opera Homes: Music, Acoustics, and Structure by Leo Beranek):
Montreal’s Salle Wilfrid-Pelletier
- Quantity: 936,000ft3
(26,500m3) - Peak: 77ft (23.5m)
- Width: 108ft (32.9m)
- Size: 123ft (37.5m)
- Seats: 2,982
NYC’s Metropolitan Opera Home
- Quantity: 24,724m3
- Seats: 3,816
Milan’s La Scala
- Quantity: 11,252m3
- Seats: 2,289
Paris’s Opera Garnier
- Quantity: 10,000m3
- Seats: 2,131
Vienna’s State Opera
- Quantity: 10,665m3
- Seats: 1,709
Primarily based on these numbers and contemplating different elements resembling kind of floor and form of the corridor, listed here are a number of the acoustical issues noticed at SWP:
The excessive and semi-opened ceiling doesn’t enable satisfactory reflections as a result of the sound has to journey too far earlier than it hits a floor and doesn’t replicate sufficient vitality again to the primary flooring. The sound stays trapped on the stage and muddles up the music.
There aren’t any laborious surfaces to the facet of the proscenium, so no lateral reflections of the sound vitality towards the primary flooring.
Though the Metropolitan Opera Home possesses the biggest variety of seats, SWP is the largest in measurement requiring extra quantity from the sound supply with a purpose to be heard all through the corridor.
Microphones
When choosing up the sound of the operatic voice, microphones have to be as impartial as doable. Throughout our go to to SWP, Neumann shotgun condenser microphones have been positioned on the ground alongside the nostril of the stage, on the sting of the pit. Typically microphones have to be camouflaged inside the set to choose up the voices of singers who’re located towards the again of the stage or behind the scenes. By putting the microphones a couple of ft from the singers, the sound picked up is extra pure than if the microphones have been positioned on the singers or if the singers wore headset microphones. With this sound system, it’s essential to comply with the actions of singers on stage, to amplify solely the microphones near the singers when they’re singing and to close off microphones that aren’t in use. To perform this, the sound engineer must function the mixer all through the present. if all of the microphones have been simply left open all through the sound can be of poor high quality, as a result of a voice that enters a number of microphones positioned at completely different distances creates an unnatural part within the sound.
The loudspeakers
For a rock live performance, the general public deal with system (PA) alone is chargeable for driving the excessive sound strain stage anticipated on this style, so the audio system must be highly effective and drive all frequency bands to all sections of the corridor. Consequently, the PA is far louder than the supply sound coming from the stage.
Within the case of opera, the primary sound supply comes from the musicians on the stage. The PA is used to direct sound exactly to the components of the corridor that want it. This kind of loudspeaker is ready to management which frequency bands can be strengthened (bass, medium, treble) and ship them to the completely different sections of the room that want it. The PA might additionally assist to compensate for the reverb that’s naturally lacking within the corridor. In opera, the PA must not ever equal or surpass the extent of the sound on stage, or the outcome would sound compelled and unnatural. In crossover genres, this sort of strategy is important and makes the singer’s voice sound “bigger than life”—for instance that of Andrea Bocelli.

Sound reinforcement for the artists
Sound reinforcement of an opera is usually additionally mandatory for the artists who sing on stage. Singers who transfer on stage want to have the ability to hear the orchestra within the pit on a regular basis. To do that, the sound of every part of the orchestra is picked up by microphones and is redirected to audio system hidden on the stage in order that the singers are capable of hear the orchestra correctly, even when they’re singing inside the set.
Economical and sensible causes have lately made using microphones prevalent in some trendy opera homes, primarily to compensate for the acoustical flaws in some multipurpose trendy theatres. There may be additionally the tendency and notion that “louder is healthier.” Trendy audiences are accustomed to loud leisure: TV, pop concert events, music, headphones, and so on. This might be unconsciously pushing opera producers to mic it up and switch it up.

Now we have loud television’s, loud pop concert events, music in every single place.,
headphones… This seek for loud and for brand spanking new public might be even be unconsciously pushing opera producers to mic it up and switch it up.
