Search "Roland, Peter S. (2004). Ototoxicity" on Google Books (https://books.google.com/) and it's the first result. If you search salicylate there's load on interesting information regarding aspirin and hearing.
Page 173 states that aspirin when administered with gentamicin in hamsters is actually otoprotective (benefical to the ear) rather than ototoxic (harmful to the ear)(page 173).

I find this interesting, considering Peat's positive view of aspirin and antibiotics and how this shows that when combined, aspirin and antibiotics (specifically gentamicin), the result is beneficial to hearing and the ear.

ASA ingestion of ≥1.95 g per day is associated with worse audiometric results (4–112 dB threshold shift), and data suggest that the effect is dose-dependent and reversible in the short term. There are no audiometric data that confirm that long-term doses of 81 mg or 325 mg daily have no hearing consequences and no data to suggest that these doses should be stopped in the setting of hearing loss. Paradoxically, ASA (in doses shown to be detrimental in isolation) has a protective effect when co-administered with intravenous gentamicin. With the large-scale population utilization of aspirin for cardiovascular prophylaxis, the potential risks to hearing health should be considered for future longitudinal study, particularly given that short-term effects may be reversible.
