What is reverberation time (RT60) and why is it important for HDB room acoustics?
Reverberation time (RT60) measures how long it takes for sound to decay by 60 dB in a room. A suitable RT60 ensures speech clarity and music enjoyment in your HDB flat, preventing echoes and muddiness.
What is Speech Transmission Index (STI)?
Speech Transmission Index (STI) measures speech intelligibility in a room. A high STI score indicates clear and understandable speech, crucial for living rooms and home offices in HDB flats.
What is background noise level and how does it affect HDB room acoustics?
Background noise level refers to the ambient noise present in a room, such as traffic or appliance noise. Lower background noise levels improve speech intelligibility and reduce distractions, enhancing overall acoustic comfort in your HDB flat.
What is sound absorption coefficient and how is it relevant to HDB renovation?
The sound absorption coefficient measures a materials ability to absorb sound energy. Using materials with high absorption coefficients, like acoustic panels or thick curtains, reduces reflections and reverberation, improving acoustics in your HDB renovation.
What are flutter echoes and how can they be minimized in an HDB room?
Flutter echoes are distinct, repeating echoes that occur between parallel surfaces. They can be minimized by introducing diffusion elements like bookshelves or angled panels, or by adding absorption materials to break up the sound waves in your HDB room.
