LB 3669 from lk fall 80 set; d1t1 with not much above 8k except strong hiss band; then the hiss band goes away and increases to about 13k and then at d2t5 increases to 16k; seems to be same recording as LB-499 with same talking at begin of d1t3; in comparison to LB-499 this has the advantage of being complete with d1t4; this is more muffled sounding on d1t1, on d1t9 seemed less muffled but not as full or natural sound, and on d2t7 seemed harsher and had more hiss; (did not listen to all of this)
