摘要：

The angular power spectrum of the cosmic microwave background has been measured out to a sufficiently small angular scale to encompass a few acoustic oscillations. We use a phenomenological fit to the angular power spectrum to quantify the statistical significance of these oscillations: we find the evidence for acoustic oscillations is not yet compelling. We discuss the cosmological implications of such a finding.
