Aural memory is fragile
Aural memory is resilient.Especially when it was trained professionally or by our personal musical history.
What is not robust is aural memory for arbitrary sounds, music you dont know or you hear in another set of acoustical environment than your own...
For music you know by heart in your own set of acoustics parameters ( in the system/ room of the owner's) aural memory is robust...
The only one who contest that are ASR ideologues for their site marketing..
Another thing aural memory is stored in the unconscious deep layers of the body and manifested as feelings...
When i tuned my room this body/ memory guides me...Not my short term aural memory for arbitrary sounds..
Auditory Reserve and the Legacy of Auditory Experience
https://pmc.ncbi.nlm.nih.gov/articles/PMC4279143/
«We further theorize that the Auditory Reserve is an emergent property of the auditory system, such that it reflects both the flexibility and durability of the networks comprising the auditory system.
By calling it a reserve, we are implying that the Auditory Reserve reflects neural resources that are accumulated over time and moreover that these resources may not be utilized only when needed.»
Rapid formation of robust auditory memories: insights from noise
https://pubmed.ncbi.nlm.nih.gov/20510864/
«Before a natural sound can be recognized, an auditory signature of its source must be learned through experience. Here we used random waveforms to probe the formation of new memories for arbitrary complex sounds. A behavioral measure was designed, based on the detection of repetitions embedded in noises up to 4 s long. Unbeknownst to listeners, some noise samples reoccurred randomly throughout an experimental block. Results showed that repeated exposure induced learning for otherwise totally unpredictable and meaningless sounds. The learning was unsupervised and resilient to interference from other task-relevant noises. When memories were formed, they emerged rapidly, performance became abruptly near-perfect, and multiple noises were remembered for several weeks. The acoustic transformations to which recall was tolerant suggest that the learned features were local in time. We propose that rapid sensory plasticity could explain how the auditory brain creates useful memories from the ever-changing, but sometimes repeating, acoustical world.»
