If I stand at the corner of a largely room with a room-temperature and burn something with flames for few seconds, it'll hardly change the temperature of the other corner far away. Yet, If I whistled event softly it could be clearly heard at any point in the room -instantly-. Each phenomena occurs due to the disturbance of air molecules and the kinetic energy is carried away (by waves??). So how come the effect of the later is much sharper? Is it because humans are more sensitive to sound-change(volume) than thermal change?
