Solutions Made EASY
Nan Chiau Primary School was established in March 1947, is one of the six schools run by Singapore Hokkien Huay Kuan. It aims to be an innovative school where inspiring educators nurture future-ready leaders with values by fostering leadership, cognitive, physical, aesthetic, social and moral growth of students. Nan Chiau Primary school has a current total school population of 2000, including its staff and students, and is located at Seng Kang, the east side of Singapore.
The new sound system and design in Nan Chiau Primary School’s Kong Chian Hall have increased clarity of the sound produced, allowing students and staff to be more fully immersed into activities, with the system blending into its’ environment naturally.
Nurturing future-ready and all-rounded leaders are Nan Chiau Primary’s long-term aim. Therefore, they called for tenders and we were selected based on our design that provides brand-new sound system – a system with better coverage and no feedback.
With their previous sound system causing sound feedback issues,not having enough coverage (not being able to cover the upper balcony), audio interference and low frequency ramblings, Nan Chiau Primary hopes to ensure the students and staff will be able to enjoy and immerse themselves in the activities taking place during school assembly/events in the hall fully, without any technical disruptions and with a high-quality sound effect system.
Challenges We Faced
Nan Chiau Primary’s Kong Chian Hall is a squarish multi-purpose school hall which comprises upper, upper sides, lower balcony seating area with the main assembly area. The hall ambiance is relatively "echoish" and the sound is able to resonate the high ceiling, reflective walls, and floor. We needed to design a suitable sound system that is wide enough to cover the entire hall and is able to give good sound coverage to all areas as well.
After being successfully awarded the tender,and discussion with the relevant teacher-in-charge about their needs, we arrive upon an end-to-end solution from Apart Audio. The key desire from Nan Chiau Primary was for the new sound system that is able to produce a high-quality sound effect without feedback and distortion for the school assembly and events that is taking place at the hall, which was what we revolve around when thinking up of the solution.
By implementing a new sound system design, we increased the sound coverage to cover the entire hall evenly including its upper, lower balcony and the main assembly area. The lower balcony is also being covered with 4x Apart Audio Mask-6, 6- inch box speakers in relative to the frontal, to ensure that those sitting at the back is able to hear the speaker(s) clearly and not feel left out.
Not only that, the new sound system design and the new speakers helped to reduce the feedback as it eradicated the problem of reverberation, allowing people in the hall to enjoy the activities clearly and comfortably. In addition to these, the 2 AP ART MASK8F-BL 8" design two-way loudspeaker for suspend, blends in with the hall wall's color, fitting in perfectly with the decor.
After implementing the new sound system design and changing the entire school hall’s sound equipment, we tested it out during the school’s Hari Raya celebrations. With more than 5 mics (4x headworn, 1x handheld) being used concurrently, there was no feedback, even sound coverage from all sides of the hall ( though slightly muffled at the far back of level 1 and could be clearer at level 2 upper area) and with no audio interference, the client is satisfied and in our survey, they gave as an “impressive” remark.
The Staff of Nan Chiau Primary School says...
“Impressive (sound system)” “Good services!”
“The service is prompt and the sound engineers know what they are doing and provided good suggestions when faced with a problem. They are willing to take time to explain to us.”
