Music and Speech Hall
Design and Consultancy Silencing the Voice / Speech Acoustics In space, Live Music, Home Theater, Hall, Auditorium Hall
In general, multi-purpose hall used as a place for speeches, live music, choirs, parties and home theater. Problems that often happens is the audience / participants can not hear clearly articulated voice in the hall.
The seating arrangements of participants / spectators who may be standing / standing, portable, conference / classroom or sitting can also be influential. The use of sound reinforcement system or not is also influential. Greatly regret when the important moments in your event not conveyed clearly to the participant or spectator you, then VCC is present to provide an integrated solution in the space.
Sustainability Design to Achieve Psychology and Physiology Benefit
The interaction between the elements of physics, namely acoustic, light, airflow and temperature. With architectural elements that shape, texture and color. And with electronic elements, namely audio video devices in a room can give the benefit of psychology and physiology.
To achieve the above we form an integrated consulting services consisting of power KONS
Ultan with the educational background of engineering physics and architecture. Besides consultants involved have experience and delight in the related fields.
Software And Tools
Consultant & Designer
To design the room with good sound quality required determination of acoustic parameters that are customized to the allotment of the room. For example, room acoustics parameters of classical music concerts of different parameters seminar room.
The acoustics are important parameters in the design of a room are: SPL, RT60, D50, and C80. Room Acoustic Modeling can be predicted output the acoustic parameters of the room. By doing Room Acoustic Modeling in the design stage of the building owners could save the cost of design errors and can optimize the sound quality heard by the audience in the room.
Tampilan Room Acoustic Modeling
SOUND PRESSURE LEVEL (SPL)
Sound Pressure Level (SPL) meter is one of the parameters that are important in designing a room. Sound Pressure Level Distribution fairly evenly at every point makes an audience and perfomer can hear the same sound clarity. The picture below is a sample output SPL prediction mapping on a multipurpose hall.
REVERBERATION TIME (RT60)
Reverberation Time (RT60) is the time decay of 60dB in need an impulse noise in the room. Reverberation Time is crucial comfort performer and the audience to follow the proceedings. Reverberation Time fitting, can improve mood performer and audience. The picture below is a sample output graph decay impulse noise in a room.
Definition (D50) and Clarity (C80)
Definition is the listener’s ability to distinguish the sound of each instrument in a musical performance in a transient state, the basic tone and harmonics began forming so that the possibility of variations in the spectrum. Definition is the listener’s ability to distinguish the sound of each instrument in a musical performance in a transient state, the basic tone and harmonics began forming so that the possibility of variations in the spectrum. Definition is also a criterion in determining the clarity of speech in a room by utilizing the concept of energy utilized comparison with the total sound energy in the room. D50 is the ratio between the energy received in the first 50 ms with the total energy received. Length 50 ms called the boundary of acceptable speech clarity. The greater the D50 value the better the clarity level talks, as more and more sound energy utilized in 50 ms.
Clarity is measured by comparing the sound energy is utilized (which came about 0:05 to 0:08 seconds after the direct sound) with the sound reflections that come later, with reference to the assumption that the sound that captured the listener in a conversation is between 50-80 ms and noise coming thereafter considered damaging noise.
