HK01 · 2 SOURCESabout 1 hour ago10 MIN
Summary
A Hong Kong District Court has rejected a neighbor's application to introduce expert testimony in a civil lawsuit alleging noise nuisance from piano playing. Liver cancer specialist Dr. Pan Dongping and his family face legal action from On Ning, who lives in the unit below the Pan family's residence at Belcher Bay (貝沙灣). The plaintiff sought to have an expert measure noise levels using a standardized tapping machine, but the court found the proposed methodology did not accurately reflect real piano playing conditions .
Key Points
- The plaintiff is On Ning, who occupies the unit beneath the Pan family's residence at Belcher Bay Road 28, Belcher Bay .
- Five defendants were named: Dr. Pan Dongping, his wife Peng Yongzhi, their two daughters, and occupiers of two residential units .
- Dr. Pan Dongping is a renowned liver cancer specialist who was previously caught up in controversy over an AI platform called "Drug Safety Assurance" (藥倍安心) .
- The plaintiff applied on January 10 at the District Court for permission to introduce expert evidence measuring noise decibel levels .
- Presiding Magistrate Chiang Man-ching rejected the application, ruling that soundproofing measures and noise measurement methods were not central issues in this case .
Why It Matters
This case highlights the ongoing challenges in proving noise nuisance in Hong Kong's densely populated residential buildings, where musical activities can easily affect neighboring residents. The court's decision to reject the expert report application suggests the case may proceed on narrower grounds, potentially focusing directly on whether the piano sounds constitute unreasonable disturbance rather than technical noise measurements .
Detailed Report
The lawsuit was filed at the District Court by plaintiff On Ning against Dr. Pan Dongping and four co-defendants, seeking a court injunction to prohibit the defendants from continuing to create, cause, or permit noise and music sounds, including piano sounds, that may cause nuisance, damage, or inconvenience to others . The plaintiff also sought compensation for alleged violations of the building's deed of mutual covenant .
During the hearing on January 10, plaintiff On Ning requested permission to introduce an expert report that would assess whether the defendants had implemented adequate soundproofing measures . The proposed methodology involved using a standardized tapping machine to strike the floor of the Pan family's piano room, with speakers playing sounds while noise decibel levels were measured in the plaintiff's unit below .
However, Magistrate Chiang Man-ching expressed skepticism about the proposed testing method, questioning how tapping machine sounds could accurately replicate the nuances of actual piano performance . The defense team argued that a high-value piano could not be subjected to testing by unqualified persons, and even if one of the defendants played the instrument, the age and abilities of the performers had changed since 2015, making it impossible to recreate past conditions .
The defense further contended that standardized tapping machines and speakers fundamentally could not reproduce the authentic sounds of piano playing, as the volume, duration, and playing style of actual performances would differ significantly from artificial test sounds . The defendants also noted that even when playing the same instrument, factors such as repertoire choice—ranging from children's songs like "Old McDonald" to Beethoven compositions—would produce vastly different volume levels .
After hearing arguments from both sides, Magistrate Chiang ruled that the expert report would focus on issues that were not central to the case, specifically the effectiveness of soundproofing measures and appropriate noise measurement methodologies . The court rejected the plaintiff's application for the expert report and made no order as to costs .
