Budgies hear best between 2 and 5 kHz — and recover poorly from too much noise
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Cage placement is usually decided on light, draughts and family life. Hearing rarely features, for lack of numbers. Okanoya and Dooling published some in 1987 in the Journal of Comparative Psychology, comparing auditory thresholds across seven species — budgerigar, cockatiel, canary, starling, zebra finch and two sparrows: all peak in sensitivity in the 2 to 5 kHz band (see the study). Our housing guides sit in the bird bedding and habitat section.

A very crowded frequency band
That 2 to 5 kHz range is far from empty in a home: it holds phone ringtones, oven and washing-machine alarms, vacuum-cleaner whine, battery-powered children's toys and a good share of the consonants in human speech. What matters most is not the living room's volume but the spectral content of what happens in it. The budgerigar also has an atypical profile: its critical ratio — the ability to pull a sound out of background noise — falls from 0.5 to 2.8 kHz then rises sharply above, which makes it particularly dependent on how clean its favourite band is.
The between-species difference that changes everything
Ryals, Dooling, Westbrook, Dent, MacKenzie and Larsen compared several species' vulnerability to noise overexposure in 1999 in Hearing Research (see the study). Canaries and zebra finches recovered fully. Quail and the budgerigar retained a residual threshold shift of about 20 dB, with incomplete hair-cell recovery. At equal exposure, then, bird species are not equally exposed.
A repair capacity the human ear lacks
The encouraging side comes from Umemoto, Sakagami, Ashida and colleagues, who published in 1993 in ORL an experiment on the adult budgerigar: after exposure to 1,500 Hz at 120 dB for 98 hours, the short hair cells of the basilar papilla were destroyed, then regenerated, with hearing thresholds back to normal by day 14. Birds regrow what mammals lose for good.
What must not be concluded from this
These exposures are experimental and have no domestic equivalent: 120 dB for four days resembles no living room. No study links a domestic noise level to measured hearing loss in a pet bird. This work establishes relative vulnerability and repair capacity, not a quantified risk in your home. Species matters too: the parrot thresholds come from budgerigars and cockatiels, and no African grey or cockatoo was tested. As for the "130 to 150 dB" figures attributed to cockatoo screams and repeated everywhere, they come from no published measurement.
- 2 to 5 kHz: the peak sensitivity band across all seven species tested.
- About 20 dB of residual loss in budgerigars after overexposure, against full recovery in canaries.
- 14 days for thresholds to return to normal once hair cells regenerate.
- No data exist on real domestic noise: do not transfer laboratory figures.
In practice this shifts the placement criterion. A generally lively room with no repetitive high-pitched source beats a quiet room where an alarm sounds ten times a day a metre from the cage. Neighbour and overall-level questions are covered in our guide to birds in a flat, and the effect of continuous background sound in the one on music and ambient noise. How finely these species discriminate voices is covered in our article on individual contact calls.
Frequently asked questions
Does a budgie hear better than a human?
Not overall. Its useful range is narrower, centred on 2 to 5 kHz, but within it the bird discriminates very fine variations.
Do birds recover from acoustic trauma?
Partly, and it depends on species: canaries recover fully, budgerigars keep a residual deficit under the conditions tested.
Where should the cage go relative to the television?
No study sets a distance. The reasoning from these data is to move away repetitive high-pitched sources in particular, rather than continuous background sound.
