Key insights

• 👂 Tinnitus is the perception of noise without an external source, It has been a problem since Ancient Babylon, Roughly 1 in 7 people worldwide experiences tinnitus
• 🔊 Tinnitus is often caused by internal nerve signals, not external sound waves, Central nervous system generates self-produced nerve signals that are essential for hearing
• 🐾 All mammals have ongoing neural activity in their hearing pathways, Changes in neural activity allow the brain to distinguish between silence and sound, Damage to cochlear cells from loud noises, diseases, toxins, and aging can reduce auditory system sensitivity
• 🧠 Weaker nerve signals from environmental sounds can be lost completely, The brain devotes more energy to monitoring the hearing pathway to compensate, Increased background neural activity helps process weak auditory inputs and modifies the baseline for silence, Subjective tinnitus is a common symptom of various ear disorders
• 😞 Subjective tinnitus is not necessarily negative, It can trigger distressing feelings and worsen PTSD, insomnia, anxiety, and depression, No known cure for subjective tinnitus, Developing neutral associations with the sound is crucial
• 🎶 Informational masking uses soothing sounds to distract from tinnitus., Energetic masking uses sounds with the same frequency as tinnitus to occupy neurons., Practiced alongside counseling, these interventions help people re-evaluate their relationship with tinnitus., Tinnitus reveals that the brain is constantly analyzing the world and fails to filter its own internal noise.

Q&A

• How can tinnitus be managed?

  Masking tinnitus involves using auditory signals to distract the brain, and it can help people re-evaluate their relationship with tinnitus. Informational masking uses soothing sounds to distract from tinnitus. Energetic masking uses sounds with the same frequency as tinnitus to occupy neurons. Practiced alongside counseling, these interventions help people re-evaluate their relationship with tinnitus.

• What is subjective tinnitus and its effects?

  The brain compensates for weaker nerve signals from environmental sounds by increasing background neural activity, leading to subjective tinnitus, which is a common symptom of various ear disorders. Subjective tinnitus can trigger distressing feelings and worsen PTSD, insomnia, anxiety, and depression, but developing neutral associations with the sound is crucial.

• How does damage to the auditory system lead to tinnitus?

  All mammals have ongoing neural activity in their hearing pathways. Changes in this activity allow the brain to distinguish between silence and sound. Damage to cochlear cells from loud noises, diseases, toxins, and aging can reduce the sensitivity of the auditory system.

• What causes tinnitus?

  Many cases of tinnitus are caused by internally generated nerve signals rather than external sound waves affecting the ear. The central nervous system plays a significant role in producing these self-generated signals.

• What is tinnitus?

  Tinnitus is the perception of a noise like ringing, buzzing, hissing, or clicking that occurs without any external source of sound. It has been bothering humanity since Ancient Babylon, and approximately one in seven people worldwide experiences this auditory sensation.
